New computer simulations suggest that an intact Moon could have been captured within hours of a giant collision between early Earth and a Mars-sized body. The study is a proposal about one possible ...

Earth’s Moon may have formed intact within five hours of a giant impact 4.5 billion years ago, as new modeling reveals the ...

Treating ancient Earth and Theia as solid geological bodies transforms simulations of the collision that may have created the ...

Impact simulations could change how researchers understand moon formation and may help constrain the timing of the event.

A half century after NASA's Apollo 17 lunar module lifted off the moon's northeastern near side quadrant, planetary scientists still don't completely understand when or how our moon first formed. They ...

New simulations suggest the moon may have formed almost instantly after a giant impact, not slowly from a debris disk.
