Pondering questions such as What is in an exoplanet name Asteroid 2005 YU55 Asteroid 2005 YU55 will pass the Earth and Moon over the next 24 hours or so . It is roughly 400 metres in diameter and the closest it gets to us is something like 300,000 km . The closest it will get to the Moon is roughly 240,000 km . That is a long , long way away from either despite what an excited person in my blog comments insists . It won't hit the Earth and it won't hit the Moon Although 2005 YU55 passes within the orbital distance of the Moon , it doesn't actually get between the Earth and Moon at any point . It goes past them both . Also , space has a third dimension and 2005
