Theia (/ ˈ θ iː ə /) is a hypothesized ancient planet in the early Solar System which, according to the giant-impact hypothesis, collided with the early Earth around 4.5 billion years ago, with some of the resulting ejected debris coalescing to form the Moon.
Theia, an ancient planet, collided with Earth to form the moon, scientists believe. A new study suggests Theia could have also formed mysterious blobs called large low-velocity provinces, or LLVPs.
The impactor planet is sometimes called Theia, named after the mythical Greek Titan who was the mother of Selene, the goddess of the Moon. [ 2 ] Analysis of lunar rocks published in a 2016 report suggests that the impact might have been a direct hit, causing a fragmentation and thorough mixing of both parent bodies.
"It is incredible because we can uncover relics of another planet - Theia - if we dig deep enough in Earth's mantle," added planetary scientist and study co-author Hongping Deng of the Chinese ...
4.5 billion years ago, Earth experienced a cataclysmic rendezvous with a planet named Theia. Evidence of the impact is still buried deep within the Earth. 2% of Earth's Mass May Be Debris From the ...
Planet V, a planet thought by John Chambers and Jack Lissauer to have once existed between Mars and the asteroid belt, based on computer simulations. Various planets beyond Neptune: Planet Nine, a planet proposed to explain apparent alignments in the orbits of a number of distant trans-Neptunian objects. Planet X, a hypothetical planet beyond ...
A terrestrial planet must be the right size, like Earth and Venus, in order to retain an atmosphere. On Earth, once the giant impact of Theia thinned Earth's atmosphere, other events were needed to make the atmosphere capable of sustaining life. The Late Heavy Bombardment reseeded Earth with water lost after the impact of Theia. [42]
Scientists say they have found new evidence that there is a hidden planet in our solar system. For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar ...
