Phobos moon atmosphere
Webb26 sep. 2024 · The Martian moons Phobos and Deimos have been suggested to be captured asteroids based on the similarities between the dark, red, nearly featureless spectra of these bodies and D-class asteroids.However, the capture hypothesis suffers from difficulties associated with the shapes and inclinations of the Martian moons’ orbits. Webb24 juli 2024 · Also, think what it would mean to see a dark moon against a bright sky. The moon would have to be blocking the scattered light from that sky, i.e. it would have to be *in* the atmosphere and very near to the ground. Our moon doesn't do that, and neither would Phobos if seen in daytime.

WebbDeimos (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).

The origin of the Martian moons is still controversial. Phobos and Deimos both have much in common with carbonaceous C-type asteroids, with spectra, albedo, and density very similar to those of C- or D-type asteroids. Based on their similarity, one hypothesis is that both moons may be captured main-belt asteroids. Both moons have very circular orbits which lie almost exactly in Mars's equatorial plane, and hence a capture origin requires a mechanism for circularizing the initi… Webb8 juli 2024 · Phobos, the innermost and larger moon, is heavily cratered, ... Atmosphere. Mars has a thin atmosphere made up mostly of carbon dioxide, nitrogen, and argon gases. To our eyes, the sky would be hazy and red because of suspended dust instead of the familiar blue tint we see on Earth.
