They’re letting just anyone into our orbit now, it seems. Astronomers last week found a new Earth moon, though they haven’t determined if it’s rock or space-junk coming home to roost. Either way, it’s got a 50-day orbit around us. I didn’t even know, as the article mentions at the end, that we’ve already got a natural satellite besides the moon – Cruithne. There’s a very nice information page on Cruithne out of the Queen’s University Astronomy Research Group. [via Skunkfuckers]
