Animation of collision between Earth (blue) and Theia (black), forming the Moon (red and gray). Bodies are not to scale. According to the giant impact hypothesis, Theia orbited the Sun, nearly along the orbit of the proto-Earth, by staying close to one or the other of the Sun-Earth system's two more stable Lagrangian points (i.e., either L 4 or ...
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.
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] Vulcan, a hypothetical planet once believed to exist inside the orbit of Mercury. Initially proposed as the ...

(Reuters) -NASA on Friday launched a spacecraft from Florida on its way to Psyche, the largest of the several metal-rich asteroids known in our solar system and believed by scientists to be the ...
A protoplanet is a large planetary embryo that originated within a protoplanetary disk and has undergone internal melting to produce a differentiated interior. Protoplanets are thought to form out of kilometer-sized planetesimals that gravitationally perturb each other's orbits and collide, gradually coalescing into the dominant planets .
The huge indent, called the 'imbrue basin,' stretches across 750 miles.
