The comet known as “Siding Spring” had a too-close-for-comfort encounter with the Red Planet this week.
Traveling at around 125,000mph, the comet missed colliding with Mars by a mere 87,000 miles. That’s about one-third of the distance between the Earth and the Moon — in astronomical terms, a very close encounter.
NASA’s Hubble Space Telescope captured the encounter in this composite image. Sadly, it will be another million years before we see comet Siding Spring again, after it completes its orbit around the sun.
