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 if Phobos crashes into Mars?

The collision would cause Earthquakes that could be felt everywhere across the planet and it would definitely be above magnitude 10 on the Richter Scale close to the impact site. The would be a shock wave but it wouldn’t be as strong as if Phobos hit Earth as Mars’ atmosphere is only 1% that of Earth.

Is Phobos larger than Deimos?

Irregularly-shaped Phobos has an average radius of seven miles (11km) and is seven times larger than Deimos. Phobos is 3,700 miles (6,000km) from Mars and has the closest orbit of any known planetary moon.

What is the size of Phobos compared to Earth?

  • Phobos has a radius of 11.267km, which is very small when compared to other moons in the solar system. The Earth is more than 574x the size of Phobos. The two Martian moons, Phobos and Deimos, are relatively small when compared to the moons of Saturn and Jupiter.

What is the distance between Earth and Phobos?

  • While our Moon orbits at a healthy distance of 384,000 kilometers from the Earth, Phobos is only 9,378 kilometers distant from Mars and Deimos is a little farther out at 23,459 kilometers.

Can Phobos be seen from Mars?

  • During a transit, Phobos can be seen from Mars as a large black disc rapidly moving across the face of the Sun. At the same time, the shadow (antumbra) of Phobos moves across the Martian surface .
