There are a number of asteriods ( 3753 Cruithne, 54509 YORP, (85770) 1998 UP1, 2002 AA29, and 2003 YN107) in orbits that are in resonance with Earth’s. The earth resonant ones don’t scare me, this one does.
This one could be a game ender for Earth....Hey... It could happen.
This is a bit off-topic, but since we’re talking about moons, it was 42 years ago tonight that Apollo 8 orbited our moon. That was the first time that human beings saw with their own eyes the backside of the moon. Frank Borman, Jim Lovell, and Bill Anders were that crew. They read the first ten passages of Genisis, a very powerful moment in the long history of the US manned space program.
On Christmas day, they left lunar orbit and Lovell reported that “there is a Santa Claus” after coming around from the backside.
Thanks!
