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.
Artist's depiction of a collision between two planetary bodies. Such an impact between Earth and a Mars-sized object likely formed the Moon.. The giant-impact hypothesis, sometimes called the Theia Impact, is an astrogeology hypothesis for the formation of the Moon first proposed in 1946 by Canadian geologist Reginald Daly.
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 researchers ran computer simulations examining the impact event, geophysical properties of the material that likely made up Theia and the evolution of Earth's mantle - the broadest of the ...
Theia, an early protoplanet the size of Mars, hit Earth in such a way that it ejected a considerable amount of material away from Earth. Some proportion of these ejecta escaped into space, but the rest consolidated into a single spherical body in orbit about Earth, creating the Moon.
How much did the Earth tilt? From 1993 to 2010, the earth is believed to have tilted 31.5 inches east, according to the study, which was published by Geophysical Research Letters.
Theia (/ ˈ θ iː ə /; Ancient Greek: Θεία, romanized: Theía, lit. 'divine', also rendered Thea or Thia ), also called Euryphaessa ( Ancient Greek : Εὐρυφάεσσα , "wide-shining"), is one of the twelve Titans , the children of the earth goddess Gaia and the sky god Uranus in Greek mythology .
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.
