How big is Phobos seen from Mars?
14 miles
Phobos and Deimos are so small that even in large Earth-based telescopes they appear as mere points of light. Phobos, the larger of the two, measures 14 miles (23 kilometers) across, while Deimos is just 8 miles (13 km) wide.
What is the size of Phobos and Deimos?
Phobos and Deimos bear more resemblance to asteroids than to Earth’s moon. Both are tiny — the larger, Phobos, is only 14 miles across (22 kilometers), while the smaller, Deimos, is only 8 miles (13 km), making them some of the smallest moons in the solar system.
How big is Deimos compared to Mars?
Deimos has a mean radius of 6.2 km (3.9 mi) and takes 30.3 hours to orbit Mars. Deimos is 23,460 km (14,580 mi) from Mars, much farther than Mars’s other moon, Phobos….Deimos (moon)

How big is Earth compared to Deimos?
1, 2013. The images are oriented so that north is up. The size-comparison image of Earth’s moon, on the right, is also oriented with north up. Deimos has a diameter of 7.5 miles (12 kilometers) and was 12,800 miles (20,500 kilometers) from the rover at the time of the image.
Which is bigger Phobos or Deimos?
Phobos is a bit larger than Deimos, and orbits only 3,700 miles (6,000 kilometers) above the Martian surface. No known moon orbits closer to its planet.
What is the size of Deimos?
3.8525 mi

How fast does Phobos orbit Mars?
every 7 hours 39 minutes
Phobos has an equatorial orbit, which is almost circular. It orbits once every 7 hours 39 minutes just 5989 km above the surface of Mars. Its orbit is decaying by 1.8 cm per year, so it is expected to crash into Mars, or break up to leave a ring of fragments around the planet, within 100 million years.
How long does it take Deimos to go around Mars?
30 hours
The close orbit of Deimos is nearly circular. It travels around the equatorial plane of Mars in 30 hours, a little over a Martian day.
How fast is Deimos moving away from Mars?
The close orbit of Deimos is nearly circular. It travels around the equatorial plane of Mars in 30 hours, a little over a Martian day.
