What is the distance between Phobos and the Sun?
Sun-Mars distance is 1.523679 AU = 2.279391 E+08 km, nearly. Phobos (nearly circular) orbit-average-distance from Mars is 9376 km, nearly. Add and subtract this from Sun-Mars distance.
What is the distance from Deimos to the Sun?
=1.5241565 AU from Sun at its maximum.
How far apart are Phobos and Deimos?

How are Phobos and Deimos different from Earth’s moon?
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.
Do Phobos and Deimos have gravity?
In 1877, the American astronomer Asaph Hall discovered two small moons circling the planet Mars. They were named Phobos (Fear) and Deimos (Panic). Their small size means that gravity on both moons is very weak. …
How far is Phobos from Earth?
48.34 million mi
Phobos/Distance to Earth
How far away are Phobos and Deimos from Mars?
At a distance of 14,573 miles (23,460 km), Deimos is more than twice as far from Mars than Phobos.

What makes Phobos different from most other moons?
Phobos (pronounced FOH bus) is the largest of the two moons which orbit the planet Mars. It is also closer to it’s primary than any other satellite in the solar system. Phobos travels only 3,700 miles (6,000 km) above the surface of the red planet – by comparison the Moon is 384,400 km above Earth.
Why are Phobos and Deimos so small?
They were named Phobos (Fear) and Deimos (Panic). More than 130 years later, scientists are still trying to unravel the mysteries of these moons. They may be asteroids – small rocks left over from the birth of the planets – that were captured by Mars. Their small size means that gravity on both moons is very weak.
How close is Phobos to Mars?
6,000 km
Phobos orbits 6,000 km (3,700 mi) from the Martian surface, closer to its primary body than any other known planetary moon. It is so close that it orbits Mars much faster than Mars rotates, and completes an orbit in just 7 hours and 39 minutes.
What is the distance between Mars’ Phobos and Deimos?
[ Mars Rover Sees Phobos and Deimos (Video)] Deimos orbits a bit farther out, at a distance of 12,400 miles (20,000 km). Interestingly, because of the two moons’ extreme closeness to their host planet, there are actually parts of Mars from which Phobos and/or Deimos would not be visible — the bulge of Mars’ own curvature gets in the way!
What is the size of the moon Phobos?
Overview. Phobos is the larger of Mars’ two moons and is 17 x 14 x 11 miles (27 by 22 by 18 kilometers) in diameter. It orbits Mars three times a day, and is so close to the planet’s surface that in some locations on Mars it cannot always be seen.
How many nights did it take to find Phobos and Deimos?
He discovered Deimos the next night, and Phobos six nights after that. The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter took two images of the larger of Mars’ two moons, Phobos, within 10 minutes of each other on March 23, 2008.
How many times a day does Phobos orbit Mars?
It orbits Mars three times a day, and is so close to the planet’s surface that in some locations on Mars it cannot always be seen. Phobos is nearing Mars at a rate of six feet (1.8 meters) every hundred years; at that rate, it will either crash into Mars in 50 million years or break up into a ring.
