[1] [2] Collision simulations support the idea that the large low-shear-velocity provinces in the lower mantle may be remnants of Theia. [3] [4] Theia is hypothesized to have been about the size of Mars, and may have formed in the outer Solar System and provided much of Earth's water, though this is debated. [5]
If a separate proto-planet Theia had existed, it probably would have had a different oxygen isotopic signature than Earth, as would the ejected mixed material. [51] The Moon's titanium isotope ratio (50 Ti/ 47 Ti) appears so close to Earth's (within 4 ppm), that little if any of the colliding body's mass could likely have been part of the Moon ...
On Twin Earth, there is a Twin equivalent of every person and thing here on Earth. The one difference between the two planets is that there is no water on Twin Earth. In its place there is a liquid that is superficially identical, but is chemically different, being composed not of H 2 O, but rather of some more complicated formula which we ...
According to the giant impact hypothesis, the Moon formed after a collision between two co-orbital objects: Theia, thought to have had about 10% of the mass of Earth (about as massive as Mars), and the proto-Earth. Their orbits were perturbed by other planets, bringing Theia out of its trojan position and causing the collision.

An Earth analog, also called an Earth twin or second Earth, is a planet or moon with environmental conditions similar to those found on Earth. The term Earth-like planet is also used, but this term may refer to any terrestrial planet. The possibility is of particular interest to astrobiologists and astronomers under reasoning that the more ...
Early accounts gave her a primal origin, said to be the eldest daughter of Gaia (Earth) and Uranus (Sky). [4] She is thus the sister of the Titans (Oceanus, Crius, Hyperion, Iapetus, Coeus, Themis, Rhea, Phoebe, Tethys, Mnemosyne, Cronus, and sometimes of Dione), the Cyclopes, the Hecatoncheires, the Giants, the Meliae, the Erinyes, and is the half-sister of Aphrodite (in some versions ...
