Solar System portal. In the astronomical literature, the term 'closest planets' often means 'the two planets that approach each other most closely'.
In other words, the orbits of the two planets approach each other most closely. However, this does not mean that the two planets are closest over time.
Essentially because Mercury is closer to the Sun than Venus, Mercury spends more time in proximity to Earth; it could, therefore, be said that Mercury is the planet that is 'closest to Earth when averaged over time'.
However, using this time-average definition of 'closeness', it turns out that Mercury is the closest planet to all other planets in the solar system.
For that reason, arguably, the proximity-definition is not particularly helpful. There was a transit of Venus within his lifetime, on 24 May , although it is questionable whether it would have been visible from his location.

Archived from the original on 19 June Geophysical Research Letters. Bibcode : GeoRL.. Toen Galileo Galilei manen rond Jupiter ontdekte werd ook de maan van de Aarde niet langer als planeet gezien.
Lange tijd werd "elk hemellichaam dat rond de Zon draaide en niet rond een ander hemellichaam" als planeet geclassificeerd.
Later is deze definitie geregeld gewijzigd en verder gespecificeerd. Het zonnestelsel bevat acht planeten. Vanaf de zon gezien zijn dat genummerd volgens afbeelding rechts :.
Vrijwel alle planeten zijn in Europese talen vernoemd naar Romeinse goden. De enige uitzonderingen zijn Uranus vernoemd naar een Griekse godheid en de Aarde.
Over de naamgeving van planeten buiten het zonnestelsel bestaat geen eenduidigheid. Veelal wordt de naam of aanduiding van de ster waar de planeet omheen draait, gebruikt, voorzien van een extra letter.
Een planeet die om een andere ster dan de Zon wentelt, heet exoplaneet. Exoplaneten zijn moeilijk waar te nemen: ze zijn uiterst lichtzwak omdat ze doorgaans kleiner zijn dan sterren en uitsluitend weerkaatst licht uitzenden, en ze bevinden zich bovendien dicht bij de veel lichtsterkere centrale ster.
De eerste onrechtstreekse waarnemingen die het bestaan van exoplaneten bevestigden, dateren uit de jaren Pas sinds zijn er rechtstreekse waarnemingen.
Naast directe waarneming onderscheidt men de volgende methoden om exoplaneten te vinden :. Op basis van samenstelling kunnen planeten worden ingedeeld in aardse of terrestrische planeten , gasreuzen of ijsreuzen.
Another criterion for separating planets and brown dwarfs, rather than deuterium fusion, formation process or location, is whether the core pressure is dominated by coulomb pressure or electron degeneracy pressure.
After much debate and one failed proposal, a large majority of those remaining at the meeting voted to pass a resolution.
The resolution defines planets within the Solar System as follows: . A "planet"  is a celestial body that a is in orbit around the Sun, b has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium nearly round shape, and c has cleared the neighbourhood around its orbit.
Under this definition, the Solar System is considered to have eight planets. Bodies that fulfill the first two conditions but not the third such as Ceres, Pluto, and Eris are classified as dwarf planets , provided they are not also natural satellites of other planets.
Originally an IAU committee had proposed a definition that would have included a much larger number of planets as it did not include c as a criterion.
This definition is based in theories of planetary formation, in which planetary embryos initially clear their orbital neighborhood of other smaller objects.
As described by astronomer Steven Soter : . The IAU definition presents some challenges for exoplanets because the language is specific to the Solar System and because the criteria of roundness and orbital zone clearance are not presently observable.
Astronomer Jean-Luc Margot proposed a mathematical criterion that determines whether an object can clear its orbit during the lifetime of its host star, based on the mass of the planet, its semimajor axis, and the mass of its host star.
The table below lists Solar System bodies once considered to be planets but no longer considered as such by the IAU, as well as whether they would be considered planets under Stern's and definitions.
Ceres was subsequently classified by the IAU as a dwarf planet in The reporting of newly discovered large Kuiper belt objects as planets - particularly Eris - triggered the August IAU decision on what a planet is.
The names for the planets in the Western world are derived from the naming practices of the Romans, which ultimately derive from those of the Greeks and the Babylonians.
In ancient Greece , the two great luminaries the Sun and the Moon were called Helios and Selene ; the farthest planet Saturn was called Phainon , the shiner; followed by Phaethon Jupiter , "bright"; the red planet Mars was known as Pyroeis , the "fiery"; the brightest Venus was known as Phosphoros , the light bringer; and the fleeting final planet Mercury was called Stilbon , the gleamer.
The Greeks also made each planet sacred to one among their pantheon of gods, the Olympians : Helios and Selene were the names of both planets and gods; Phainon was sacred to Cronus , the Titan who fathered the Olympians; Phaethon was sacred to Zeus , Cronus's son who deposed him as king; Pyroeis was given to Ares , son of Zeus and god of war; Phosphoros was ruled by Aphrodite , the goddess of love; and Hermes , messenger of the gods and god of learning and wit, ruled over Stilbon.
The Greek practice of grafting their gods' names onto the planets was almost certainly borrowed from the Babylonians. The Babylonians named Phosphoros after their goddess of love, Ishtar ; Pyroeis after their god of war, Nergal , Stilbon after their god of wisdom Nabu , and Phaethon after their chief god, Marduk.
For instance, the Babylonian Nergal was a god of war, and thus the Greeks identified him with Ares. Unlike Ares, Nergal was also god of pestilence and the underworld.
Today, most people in the western world know the planets by names derived from the Olympian pantheon of gods.
Although modern Greeks still use their ancient names for the planets, other European languages, because of the influence of the Roman Empire and, later, the Catholic Church , use the Roman Latin names rather than the Greek ones.
The Romans, who, like the Greeks, were Indo-Europeans , shared with them a common pantheon under different names but lacked the rich narrative traditions that Greek poetic culture had given their gods.
During the later period of the Roman Republic , Roman writers borrowed much of the Greek narratives and applied them to their own pantheon, to the point where they became virtually indistinguishable.
Uranus is unique in that it is named for a Greek deity rather than his Roman counterpart. Some Romans , following a belief possibly originating in Mesopotamia but developed in Hellenistic Egypt , believed that the seven gods after whom the planets were named took hourly shifts in looking after affairs on Earth.
Because each day was named by the god that started it, this is also the order of the days of the week in the Roman calendar after the Nundinal cycle was rejected — and still preserved in many modern languages.
Earth is the only planet whose name in English is not derived from Greco-Roman mythology. Because it was only generally accepted as a planet in the 17th century,  there is no tradition of naming it after a god.
The same is true, in English at least, of the Sun and the Moon, though they are no longer generally considered planets.
The name originates from the 8th century Anglo-Saxon word erda , which means ground or soil and was first used in writing as the name of the sphere of Earth perhaps around Many of the Romance languages retain the old Roman word terra or some variation of it that was used with the meaning of "dry land" as opposed to "sea".
Non-European cultures use other planetary-naming systems. China and the countries of eastern Asia historically subject to Chinese cultural influence such as Japan, Korea and Vietnam use a naming system based on the five Chinese elements : water Mercury , metal Venus , fire Mars , wood Jupiter and earth Saturn.
It is not known with certainty how planets are formed. The prevailing theory is that they are formed during the collapse of a nebula into a thin disk of gas and dust.
A protostar forms at the core, surrounded by a rotating protoplanetary disk. Through accretion a process of sticky collision dust particles in the disk steadily accumulate mass to form ever-larger bodies.
Local concentrations of mass known as planetesimals form, and these accelerate the accretion process by drawing in additional material by their gravitational attraction.
These concentrations become ever denser until they collapse inward under gravity to form protoplanets. When the protostar has grown such that it ignites to form a star , the surviving disk is removed from the inside outward by photoevaporation , the solar wind , Poynting—Robertson drag and other effects.
Protoplanets that have avoided collisions may become natural satellites of planets through a process of gravitational capture, or remain in belts of other objects to become either dwarf planets or small bodies.
The energetic impacts of the smaller planetesimals as well as radioactive decay will heat up the growing planet, causing it to at least partially melt.
The interior of the planet begins to differentiate by mass, developing a denser core. With the discovery and observation of planetary systems around stars other than the Sun, it is becoming possible to elaborate, revise or even replace this account.
The level of metallicity —an astronomical term describing the abundance of chemical elements with an atomic number greater than 2 helium —is now thought to determine the likelihood that a star will have planets.
According to the IAU definition , there are eight planets in the Solar System, which are in increasing distance from the Sun :. Jupiter is the largest, at Earth masses, whereas Mercury is the smallest, at 0.
The number of geophysical planets in the solar system is unknown - previously considered to be potentially in the hundreds, but now only estimated at only the low double digits.
An exoplanet extrasolar planet is a planet outside the Solar System. As of 1 December , there are 4, confirmed exoplanets in 3, systems , with systems having more than one planet.
These pulsar planets are believed to have formed from the unusual remnants of the supernova that produced the pulsar, in a second round of planet formation, or else to be the remaining rocky cores of giant planets that survived the supernova and then decayed into their current orbits.
The first confirmed discovery of an extrasolar planet orbiting an ordinary main-sequence star occurred on 6 October , when Michel Mayor and Didier Queloz of the University of Geneva announced the detection of an exoplanet around 51 Pegasi.
From then until the Kepler mission most known extrasolar planets were gas giants comparable in mass to Jupiter or larger as they were more easily detected.
The catalog of Kepler candidate planets consists mostly of planets the size of Neptune and smaller, down to smaller than Mercury. There are types of planets that do not exist in the Solar System: super-Earths and mini-Neptunes , which could be rocky like Earth or a mixture of volatiles and gas like Neptune—a radius of 1.
Another possible type of planet is carbon planets , which form in systems with a higher proportion of carbon than in the Solar System.
A study, analyzing gravitational microlensing data, estimates an average of at least 1. On 20 December , the Kepler Space Telescope team reported the discovery of the first Earth-size exoplanets , Keplere  and Keplerf ,  orbiting a Sun-like star , Kepler Around 1 in 5 Sun-like stars have an "Earth-sized" [d] planet in the habitable [e] zone, so the nearest would be expected to be within 12 light-years distance from Earth.
There are exoplanets that are much closer to their parent star than any planet in the Solar System is to the Sun, and there are also exoplanets that are much farther from their star.
Mercury , the closest planet to the Sun at 0. The Kepler system has five of its planets in shorter orbits than Mercury's, all of them much more massive than Mercury.
Neptune is 30 AU from the Sun and takes years to orbit, but there are exoplanets that are hundreds of AU from their star and take more than a thousand years to orbit, e.
A planetary-mass object PMO , planemo ,  or planetary body is a celestial object with a mass that falls within the range of the definition of a planet: massive enough to achieve hydrostatic equilibrium to be rounded under its own gravity , but not enough to sustain core fusion like a star.
These include dwarf planets , which are rounded by their own gravity but not massive enough to clear their own orbit , planetary-mass moons , and free-floating planemos, which may have been ejected from a system rogue planets or formed through cloud-collapse rather than accretion sometimes called sub-brown dwarfs.
A dwarf planet is a planetary-mass object that is neither a true planet nor a natural satellite; it is in direct orbit of a star, and is massive enough for its gravity to compress it into a hydrostatically equilibrious shape usually a spheroid , but has not cleared the neighborhood of other material around its orbit.
Planetary scientist and New Horizons principal investigator Alan Stern , who proposed the term 'dwarf planet', has argued that location should not matter and that only geophysical attributes should be taken into account, and that dwarf planets are thus a subtype of planet.
The IAU accepted the term rather than the more neutral 'planetoid' but decided to classify dwarf planets as a separate category of object.
Several computer simulations of stellar and planetary system formation have suggested that some objects of planetary mass would be ejected into interstellar space.
Stars form via the gravitational collapse of gas clouds, but smaller objects can also form via cloud-collapse.
Planetary-mass objects formed this way are sometimes called sub-brown dwarfs. Binary systems of sub-brown dwarfs are theoretically possible; Oph was initially thought to be a binary system of a brown dwarf of 14 Jupiter masses and a sub-brown dwarf of 7 Jupiter masses, but further observations revised the estimated masses upwards to greater than 13 Jupiter masses, making them brown dwarfs according to the IAU working definitions.
In close binary star systems one of the stars can lose mass to a heavier companion. Accretion-powered pulsars may drive mass loss.
The shrinking star can then become a planetary-mass object. Some large satellites moons are of similar size or larger than the planet Mercury , e.
Jupiter's Galilean moons and Titan. Proponents of the geophysical definition of planets argue that location should not matter and that only geophysical attributes should be taken into account in the definition of a planet.
Alan Stern proposes the term satellite planet for a planet-sized satellite. Rogue planets in stellar clusters have similar velocities to the stars and so can be recaptured.
They are typically captured into wide orbits between and 10 5 AU. It is almost independent of the planetary mass. Single and multiple planets could be captured into arbitrary unaligned orbits, non-coplanar with each other or with the stellar host spin, or pre-existing planetary system.
Although each planet has unique physical characteristics, a number of broad commonalities do exist among them. Some of these characteristics, such as rings or natural satellites, have only as yet been observed in planets in the Solar System, whereas others are also commonly observed in extrasolar planets.
According to current definitions, all planets must revolve around stars; thus, any potential " rogue planets " are excluded. In the Solar System, all the planets orbit the Sun in the same direction as the Sun rotates counter-clockwise as seen from above the Sun's north pole.
At least one extrasolar planet, WASPb , has been found to orbit in the opposite direction to its star's rotation.For other uses, see Planet (disambiguation).
