phobos and demos are natural satellite of which planet
Phobos (moon) Phobos (/ˈfoʊbəs/ FOH-bəs or /ˈfoʊbɒs/ FOH-bos,[4] from the Greek Φόβος.) (systematic designation: Mars I) is the innermost and larger of the two natural satellites of Mars,[5] the other being Deimos. Both moons were discovered in 1877 by American astronomer Asaph Hall.
Extraterrestrial skies Although no images from within Jupiter's atmosphere have ever been taken, artistic representations typically assume that the planet's sky is blue, though dimmer than Earth's, because the sunlight there is on average 27 times fainter, at least in the upper reaches of the atmosphere. The planet's narrow rings might be faintly visible from latitudes above the equator. Further down into the atmosphere, the Sun would be obscured by clouds and haze of various colors, most commonly blue, brown, and red. Although theories abound on the cause of the colors, there is currently no unambiguous answer.[16]
