What are the moons of Mars? Mars has several moons

2 satellites. Phobos-1, diameter 27 22 18 km, mass kg, synchronous rotation. The orbital radius is 9,376 km, the orbital period is 7 hours, 39 minutes and 1 second, and the orbital speed is meters and seconds.

After being captured by Mars, Phobos 1 accelerates during its fall, and when centrifugal force and cohesion are balanced, it orbits Mars. Therefore, the rotational velocity of Phobos 1 is greater than the vortex velocity of Mars. Phobos 1's orbital speed is now decreasing by 2 meters every 100 years, and it is estimated that in 40 million years it will crash into Mars.

Phobos-1 mass kilograms, Mars mass kilograms, orbital radius meters, revolution speed meters and seconds, g N·m2 kilograms.

Phobos-2, km in diameter, kilograms, synchronous rotation. The orbital radius is 23 460 km, the orbital period is 30 hours and 18 minutes, and the orbital speed is kilometers and seconds. The escape velocity is in meters and seconds. Temperature 233 K

Mars has two natural satellites. 1877 by A. A. of the United StatesHall discovered.

Phobos is a macro sleepy.

It is 9,370 kilometers away from the center of Mars, and its orbital period is 7 hours and 59 minutes, which is much faster than the rotation of Mars, so from Mars, it rises in the west and sets in the east.

Deimos. It is 23,500 kilometers from Mars and has a cycle of 30 hours and 18 minutes. They are all very irregular in shape, the size of Phobos is kilometers kilometers kilometers, and the mass is estimated to be kilograms.

Physical properties of Phobos.

Phobos and Deimos can be made up of carbon-rich rocks like c-type asteroids. But they can't be made up of pure rock envy, because their density is too low. They are most likely made up of a mixture of rock and ice, and they both have deep crustal pits.

Former Soviet Union. The probe Phobos 2 detected a faint but persistent gas escaping from the phobos. Unfortunately, Phobos 2 was unable to work until the composition of the gas was detected.

Water is perhaps the most likely component. Phobos No. 2 also brought back some**.

The most prominent topographical feature on the Phobos is a large pit called Stickney, which is the name of the aforementioned Hall's wife. It's like a crater on Enceladus.

Herschel (smaller in size). Stickney must have had the role of destroying Phobos.

Mars has two moons, one called Forboldan and the other Demos. Forbos and Demos are about the same as Chi Tongduo orbiting in the equatorial plane of Mars. Forbos is about 9,450 kilometers from the center of Mars, and Demos is about 23,500 kilometers from the center of Mars.

Forbos and Demos are relatively close to Mars. Forbos and Demos are only 10,000 kilometers and 10,000 kilometers from Mars. However, because Forpos and Demos are relatively small, only one percent of the diameter of the moon, they cannot produce the visual effect of seeing the moon from the earth.

Mars has moons.

A satellite refers to a celestial body that orbits a planet in a closed orbit periodically, and can be divided into artificial satellites and natural satellites. In the solar system, all planets except Mercury and Venus are orbited by moons. The Moon, as the first extraterrestrial object ever landed by humans, is a natural satellite of the Earth.

Mars, one of the eight planets in the solar system, also has two natural satellites, named after Forbes and Deimos, the sons of the god of war in ancient Greek mythology, Ares.

The situation of the two Guardian Chain stars of Mars:

Phobos is the larger of the two satellites of Mars, with a potato-like shape, a mass of about 9,378 km from Mars, an average distance of about 9,378 km, which is closer than the moons of any other known planet, with an orbital period of 7 hours and 39 minutes, and a speed around Mars that orbits Mars at a speed greater than the rate of Mars' rotation.

So Phobos can orbit Mars 3 times a day. Phobos is the farther and smaller of the two Martian moons, with a mass of 15 km, 23,459 km from Mars, and an orbital period of 30 hours and 18 minutes.

Some.

Mars has two natural satellites.

1877 by A. A. of the United StatesHall discovered. Phobos is 937 kilometers away from the central hall of Mars, and its orbital period is 7 hours and 59 minutes, which is much faster than the rotation of Mars, so from Mars, it rises in the west and sets in the east.

Phobos is 235 kilometers from Mars, with a period of 3 hours and 18 minutes, and their shapes are very irregular, with a size of 1 km and an estimated mass of 1 14 kg.

Mars has two natural satellites, Phobos is only 9370 kilometers away from the center of Mars, and the orbital period is 7 hours and 59 minutes, which is much faster than the rotation of Mars, so from the perspective of Mars, it is rising in the west and setting in the east, and Phobos is 23500 kilometers away from Mars, with a period of 30 hours and 18 minutes, and their shapes are very irregular.

Mars is one of the eight planets in the solar system, the fourth planet in the solar system from the inside to the outside, and is a terrestrial planet, with a diameter of about 53% of the Earth.
