SOLAR SYSTEM

Detailed explanation-1: -A subsatellite, also known as a submoon, or moonmoon, is a “moon of a moon” or a hypothetical natural satellite that orbits the moon of a planet.

Detailed explanation-2: -A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are colloquially referred to as moons, a derivation from the Moon of Earth.

Detailed explanation-3: -Planets orbit stars and moons orbit planets, so it was natural to ask if smaller moons could orbit larger ones. So far at least, no submoons have been found orbiting any of the moons considered most likely to support them – Jupiter’s moon Callisto, Saturn’s moons Titan and Iapetus and Earth’s own moon.

Detailed explanation-4: -Natural satellites, or moons, are objects in space that orbit around another object. Most natural satellites are moons for planets, and are mostly made of rock, but some are made of ice. One natural satellite we know of even has volcanoes.
