Well, it was several billion years ago, so surely any debris would have had more than enough time to clear out or fall down onto Earth and the Moon?

- 0xdeadb00f 5y agoCouldn't the same be said of Saturn's rings? Why have they been around for so long then?
- sprash 5y agoConsidering the timescale the asteroid belt could have formed a planet by now as well. Something doesn't add up about the established creation theory of the moon.
- emteycz 5y agoYou missed Jupiter in your calculations.
- Sharlin 5y agoAlso, the total mass of the present-day asteroid belt is only about four percent of the Moon's mass. Ceres makes up about a third of that, so one could say that the belt did form a planet – it's just that its growth was heavily stunted by Jupiter's interference.
- fogihujy 5y agoLast thing I heard, Saturn's rings are surprisingly young (about 100 million years old), and are indeed slowly disappearing.
