8 gru 2017 · Identity crisis. 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,...
Phobos (/ ˈ f oʊ b ə s /; systematic designation: Mars I) is the innermost and larger of the two natural satellites of Mars, the other being Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall .
20 lut 2022 · The Moon is 155 times bigger than Phobos and 280 times bigger than Deimos. Phobos is almost twice as big as Deimos. The Moon has an atmosphere (a very weak one). Phobos and Deimos are too small to hold one.
Compared to the Earth's Moon, the moons Phobos and Deimos are small. Phobos has a diameter of 22.2 km (13.8 mi) and a mass of 1.08 × 10 16 kg, while Deimos measures 12.6 km (7.8 mi) across, with a mass of 1.5 × 10 15 kg.
Phobos is the larger of the two moons of Mars, with a mean diameter 2 of about 22 km and an orbital radius of 9,376 km. Phobos orbits faster than Mars rotates, so it rises in the west and sets in the east as viewed from the planet’s surface. The low orbit has made it a target for robotic spacecraft orbiting Mars.

Eventually, Deimos will escape into space; Phobos is larger and closer to the planet – it rises and sets twice during a single day on Mars. Deimos is smaller and takes around 30 hours to complete a single orbit; Summary. Phobos and Deimos are the twin moons of Mars, potentially asteroid-like bodies captured by Mars and pulled into the planet ...
