GENERAL KNOWLEDGE

Detailed explanation-1: -The moon is a satellite because it moves around Earth. Earth and the moon are called “natural” satellites. But usually when someone says “satellite, ‘’ they are talking about a “man-made” satellite.

Detailed explanation-2: -We know that sound travels through a material medium like solid, liquid or gases because sound wave is a mechanical longitudinal wave, and there is no environment on the moon, i.e. there is no material medium like air present on the moon, so the sound can not travel on the moon so the moon is called silent planet.

Detailed explanation-3: -Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons. In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons.

Detailed explanation-4: -In the Solar System, we have the central Sun, a great many planets, asteroids, Kuiper belt objects, and moons. While most of the planets have moons, and some of the Kuiper belt objects and even asteroids have natural satellites that orbit them, there are no known “moons of moons” out there.
