	Did our Solar System once have another planet? \| COSMOS magazine
		And he thinks the misbehaviour of a long-lost, fifth rocky planet called 'Planet V' was the trigger that upset the gravitational balance of the belt and ejected some of its inhabitants.
		Planet V's orbit was between that of Mars and the Asteroid Belt, Chambers predicts, and it may have been smaller than Mars but larger than our Moon.
		The other side of the planet became dryer from the water filling the Pacific crater and formed the continental tectonic plates of Earth.

	Theia
		In astrophysics, Theia is the name of a hypothetical small planet that, according to one theory of the Moon's formation, collided with the Earth over four billion years ago.
		According to this theory, Theia would have been approximately Mars-sized and struck Earth at a glancing angle.
		Theia can also be a king of the Ostrogoths.

	Here and Above: Pluto Officially No Longer a Planet
		Their definition of planet was that it orbit the Sun, and that it is massive enough for gravity to have made it into a sphere.
		Ceres is not a planet, because the sphere in which Ceres is in is the asteroid belt and all the other asteroids put together is much larger than Ceres - in fact, it is about the mass of the Moon.
		People seem to behave as though "planet" was an inherent property of these objects, and that Pluto is a planet because it is a planet, and that it is that way in all our astronomical books, and there is a cartoon dog named after him and so forth.

		The interior of the planet remains active, with a thick layer of convecting yet solid mantle and an iron core that generates a magnetic field.
		Long term periodic changes in the orbit of the planet may also be responsible for the ice ages that have covered significant portions of the surface in glacial sheets.
		Initially molten, the outer layer of the planet cooled when water began accumulating in the atmosphere when the planet was about half its current radius, resulting in the solid crust.

	The planet that stalked the Earth
		According to the accepted theory of planet formation, protoearth's bigger gravitational pull means it should have guzzled up all the rocks in its vicinity.
		The model shows that the smaller planet struck the Earth a glancing blow at a speed of 40,000 kilometres per hour, exactly as suggested in earlier simulations carried out by Canup and her colleague Erik Asphaug at the University of California at Santa Cruz.
		Other growing planets in the solar system might have altered the pattern of forces around protoearth, preventing rubble from clumping together to form a planet.

		This planet, named Theia, is thought to have been smaller than the current Earth, probably about the size and mass of Mars.
		Temperatures plummeted and the crust of the planet was accumulated on a solid surface, with areas melted by large impacts on the scale of decades to hundreds of years between impact.

		This planet, which he named Vulcan after the Roman god of the forge due to its closeness to the Sun, was never observed, and Einstein's general relativity theory subsequently resolved the issue of Mercury's orbit.
		However, Pluto's mass was found to be too small to disturb the other planets' orbits significantly, and subsequent measurements by the Voyager 2 spacecraft showed that earlier calculations of Neptune's mass had been in error, leading to the irregularities observed.

		They are eventually eliminated by orbital decay and accretion by the Sun, collisions with the inner planets, or by being ejected from the solar system by near misses with the planets.
		An asteroid family is a group of minor planets that share similar orbital elements, such as semimajor axis, eccentricity, and orbital inclination.
		Centaurs will thus ultimately collide with the Sun or a planet or else they may be ejected into interstellar space after a close approach to one of the planets, particularly Jupiter.

		Theia is sometimes seen as a kind and beautiful goddess, but her blessings are sometimes to be feared.
		Worship of Theia may include prostration, and the burning of oils and incense, particularly at dawn or dusk.

	Mars and Earth: Different to the Core \| LiveScience
		The two planets are different down to their very core.
		Rock samples from Mars and the giant asteroid Vesta show they contain a lighter form, or "isotope," of silicate that is identical to those found in a primitive class of meteorites called chondrites.
		The finding is, however, consistent with the theory that our Moon was born when a Mars-sized planet, usually called "Theia," collided with early Earth.

	Planets & Space
		Ever since Pluto was discovered, its official status as a planet has been a constant subject of controversy, fueled by the past lack or a clear definition of planet.
		Some astronomers believed that Pluto is still a planet because it has moons and its own atmosphere, but recent discoveries revealed that some Kuiper Belt Objects have moons on their own as well as atmospheres.
		The resolved definition of a planet are the following: that it is in orbit around the sun; that it has sufficient mass that it assumes a nearly round shape; and that it has able to “clear the neighborhood” of debris.

	Theia - Free Encyclopedia of Thelema
		With her brother and husband Hyperion, she was the mother of Helios (the Sun), Selene (the Moon) and Eos (the Dawn).
		She seems here a goddess of glittering in particular and of glory in general, but Pindar's allusion to her as "Theia of many names" is telling, since it suggests assimilation not only to similar mother-of-the-sun goddess like Phoebe and Leto, but perhaps also to more universalizing mother-figures like Rhea and Cybele.
		Theia's mythological role as the mother of the Moon goddess Selene is referenced in the application of the name to a hypothetical planet which, according to one theory, collided with the Earth, resulting in the Moon's creation.

		Like the climax in a firework display, the event was the culmination of a 100-million-year process in which the Earth and its neighbouring planets were built through cosmic collisions between sub-planetary objects.
		The planet's surface was probably melted down to a depth of 1,000 kilometres, cloaking the Earth in a "magma" ocean that would have radiated like a red-hot furnace.
		Curiously, recent chemical research has shown that the planet Earth collided with was a twin to the Earth - scientists have called it "Theia" after the mother of the Moon in Greek mythology.

		Her star was the planet Venus, and classical writers gave her the epithet Caelestis and Urania.
		Lucian and Herodian testify that she was represented with horns, and the place-name Ashteroth-Karnaim in Gilead (Ashtoreth of the horns) is considered ample corroboration.

		Another long day is breaking on Venus as the sun rises in the west at the Soviet Venera 9 Lander site on the slope of a huge shield volcano known as Theia Mons in a vast uplifted region known as Beta Regio.
		Then it rapidly succumbed due to the combination of a carbon dioxide atmosphere up to 90 times Earth's laced with sulfuric acid, and blistering heat that approached 900° F. It was doomed to sit forever silently on that hillside strewn with sizzling, red-glowing rocks slowly frying and eroding.
		Venus is truly a world born of fire, evolved by fire, shaped by fire, and ultimately, as the Sun dies and swells up, to die by fire.
