[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]
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 ...
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 ...
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 ...
Another proposed origin for the LLSVPs is that their formation is related to the giant-impact hypothesis, which states that the Moon formed after the Earth collided with a planet-sized body called Theia. [15] The hypothesis suggests that the LLSVPs may represent fragments of Theia's mantle which sank through to Earth's core-mantle boundary. [15]
Another Trans-Neptunian planet at 1,500 AU away from the Sun, proposed by Rodney Gomes in 2012 [20] Theia or Orpheus, [21] a Mars-sized impactor believed to have collided with the Earth roughly 4.5 billion years ago; an event which created the Moon. Evidence from 2019 suggests that it may have originated in the outer Solar System. [22]
