Mars, Mercury May Have Formed From Earth and Venus

Posted by kdawson on from the brothers-under-the-skin dept.

goran72 sends along a report on a radical new theory of planet formation that suggests that Mars and Mercury were formed from the scraps of Earth and Venus. The theory has testable predictions — for example that the compositions of the rocky inner planets should be more similar than the current theory of planet formation would have them.

    All of the planets formed in the general vicinity of the sun from the same materials. OF COURSE, their cores should have a similar makeup, THEY ALL SHOULD! This does not prove anything.

    These stupid astronomers need to get a real job.
