That’s one speedy spud 🥔⁣ ⁣ NASAHubble took 13 separate exposures over 22 minutes to create this time-lapse image of tiny, potato-shaped moon Phobos (at left) orbiting around Mars. Phobos is so small that it looks like a star in these Hubble photos.⁣ ⁣ This little tater is fast, though: Phobos orbits Mars in just 7 hours and 39 minutes, which is faster than Mars rotates. The moon’s orbit is very slowly shrinking, meaning it will eventually – as in, 50 million years from now – break up under Mars’ gravitational pull, or crash onto the planet.⁣ ⁣ Poor little Phobos has already been battered: it was nearly shattered by a giant impact, and has gouges from thousands of meteorite impacts.⁣ ⁣ Here are a few more fun facts about Phobos:⁣ - It has no atmosphere.⁣ - It’s the larger of Mars’ two moons. The other moon is called Deimos.⁣ - The fine dust on Phobos’ surface cannot retain heat.⁣ ⁣ Image description: Tiny moon Phobos travels behind Mars in this image. The moon appears multiple times, ...
