Phobos & Deimos: 5 facts about weird Martian moons 🤪⁠ ⁠ ✅ If you spent a few days on Mars, you’d be surprised by the weird motion of its moons. During Deimos’ slow 66-hour journey across the sky toward the west, Phobos rapidly swishes in the opposite direction more than six times.⁠ ⁠ ✅ Phobos orbits its planet closer than any other moon in the Solar System — only 6,000 km (3728 miles) above the Martian surface (in comparison, our Moon is 384,400 km above the Earth). Deimos is on the second place among Solar System planets’ moons.⁠ ⁠ ✅ Mars will lose its moons. Phobos that slowly approaches Mars will crash into the planet or break up into a ring. Deimos, on the contrary, moves away from Mars and eventually will leave the planet’s orbit.⁠ ⁠ ✅ Although Phobos is only 1% of our Moon’s diameter, it appears about half as wide as viewed from Mars. Deimos, in its turn, seems similar to a star in size from the Red Planet.⁠ ⁠ ✅ Phobos and Deimos’ origin is still controversial and doesn't correspond with how planetary moons are typically formed.⁠ ⁠ Learn more about Phobos and Deimos on our starwalk.space website (the link is in the bio) from the new article: “Phobos & Deimos: Impossible Moons of Mars” ☝️⁠ .⁠ .⁠ .⁠ .⁠ .⁠ #mars #moons #phobos #deimos #martianmoons #redplanet #space #astronomy #nightsky #skytonight #StarWalk #stargazing #spaceisforeveryone #spacescience #spaceenthusiast #spacenews #constellations #astronomyfacts #solarsystem #astronomer #amateurastronomy #deepskyphotography #astrography #skynight #spacetoday #astronomynerd #skyatnight #spacepics #darkskyshots #spacetraveler
