Asteroid on near-miss course with Mars
No one taught these guys to label their plots, unfortunately (nice of them to put “mars” and “sun” on there though). To make it clearer, the cyan line is the probable trajectory of 2007 WD5. White dots indicate a possible position at the time it would intercept mars’ orbital, if it does.
Will there be a collision? Probably not. One in twenty eight odds, though? Those are most certainly not astronomical odds.
