Comet Siding Spring from Mars Exploration Rover Opportunity A comet fresh from the Oort cloud visited Mars on October 19, 2014. Opportunity pointed her cameras before sunset and then woke up to take this photo at 3:19 a.m. local time on sol 3817, about 2.5 hours before its closest approach to Mars. The comet makes a slightly elongated smudge across the sky -- but it is elongated in a different direction than the streaked stars in this long exposure, indicating the comet's apparent rapid motion across the Martian sky.
