A recently discovered asteroid which passed close to the Earth in November, is now headed towards a very close passage by Mars in late January, and there is a small chance that it could hit that planet. The probability of a collision is only 1 chance in 75, but scientists are excited about the possibility. If it happens, the impact would occur on January 30, 2008 at around 10:55 UT (2:55 a.m. PST).
