Is Phobos faster than Deimos?
As a consequence, as seen from the Martian equator, Phobos would appear to move far more rapidly than Deimos. In fact, Phobos would already be moving overhead just 2 hours and 48 minutes after rising. And after another 2 hours and 48 minutes, it would already setting.
How fast is Phobos moving?
Walk, don’t run, on the martian moon Phobos. A new study finds that traveling faster than about 5 kilometers per hour on some regions of the Red Planet’s largest satellite could shoot you straight off into space. Phobos (pictured) is an odd duck among our solar system’s moons.
What happens if you jump on Phobos?
5m), then you can jump over a half mile (1.4 km) straight up on Phobos, and your trip will take about 26 minutes (13 up and 13 down). So you might not be faster than a speeding bullet, or more powerful than a locomotive, but on Phobos you will be able to leap tall buildings in a single bound. And that’s something.
What will happen to Phobos in 50 million years?
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. Its most prominent feature is the 6-mile (9.7 kilometer) crater Stickney, its impact causing streak patterns across the moon’s surface.
How was Phobos formed?
It is possible that Phobos formed in situ at Mars, from ejecta from impacts on the Martian surface, or from the remnants of a previous moon which had formed from the Martian accretion disc and subsequently collided with a body from the asteroid belt.
How heavy is Phobos?

Does Phobos have water?
The cracks could contain water ice. If so, Phobos could serve as a refueling station for manned Mars-exploration missions. But observations by several spacecraft indicate that there’s less water at the surface of Phobos than in almost any other body in the solar system.
Will Phobos become a ring?
The secret came from looking at the motions of Phobos, which orbits closer to the Martian surface and is slowly spiraling into the planet. Eventually, Phobos will drop so close to Mars that the gravity of the much larger planet will pull the moon into pieces — forming a ring.
How big is Phobos?
7.0008 miPhobos / Radius
How wide is Phobos?
14.002 miPhobos / Diameter
Do Mars has 2 moons?
Deimos. Named after the Roman god of dread, Deimos is the smaller of Mars’ two moons. The larger moon of Mars, gouged and nearly shattered by a giant impact crater.
Is Phobos habitable?
Phobos, for example, is only 6 miles (10km) wide. But a tiny, habitable world is, after all, still habitable. The rest of the planets, Jupiter, Saturn, Uranus, and Neptune, are all out.
