Two spacecraft launched by NASA in 2006 will soon be in position to look for evidence of the remains of a planet named Theia that some scientists believe colided with the Earth billions of years ago resulting in the formation of our Moon.
The solar system might once have had another planet named Theia, which may have helped create our own planet's moon.Now two spacecraft are heading out to search for leftovers from this rumored sibling, which would have been destroyed when the solar system was still young."
