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.
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 ...
Relics of an ancient planet might be hiding under our feet, according to new research. Some scientists believe that a “protoplanet” named Theia collided with Earth some 4.5 billion years ago.
The ring was first formally proposed after 21 impact craters from the meteor event were found to be located along a straight band around the Earth's equator. [10] [11] Andrew G. Tomkins, [9] Erin L. Martin [9] and Peter A. Cawood, [9] working with Monash University, released a study in September 2024 that gave evidence on the existence of the ...
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 ...
