8 gru 2017 · 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. Both...
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 .
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.
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.
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.
29 mar 2024 · Phobos and Deimos are very different in terms of size and appearance. Phobos is the larger of the two moons, with a diameter of about 22.4 kilometers, while Deimos is much smaller, with a diameter of only about 12.4 kilometers.
Deimos (pronounced DEE-MOS) is the second moon orbiting the planet Mars along with Phobos. It is considered the second moon of the red planet because its orbit path is much further away than Phobos. Deimos is also the smaller of the two moons with a diameter of just 12.4 km (7.7 miles).
