WebbTIL one of the moons of Mars (Phobos) orbits Mars much faster than Mars rotates, and completes an orbit in just 7 hours and 39 minutes. From the surface of Mars it appears to rise in the west, move across the sky in 4 hours and 15 minutes, and set in the east, twice each Martian day. : r/todayilearned r/todayilearned • 26 days ago Webb18 apr. 2024 · Phobos and Deimos’s cratered surfaces suggest that they are ancient objects formed ~4 billion years ago . Integrating back in time from Phobos’s current orbit at 2.8 R M implies that it formed at a distance of ~5 to 6 R M, whereas Deimos’s orbit has expanded only slightly over its history to its current orbit at 6.9 R M . WebbPhobos is steadily spiraling inward due to the tides it raises, and will suffer tidal disruption before colliding with Mars. We calculate the surface stress field of the de-orbiting satellite and show that the first signs of tidal disruption are already present on its surface. diamond painting kits for adults sunflowers
