SOLAR SYSTEM

Detailed explanation-1: -Earth’s Moon is the fifth largest of the 200+ moons orbiting planets in our solar system. Earth’s only natural satellite is simply called “the Moon” because people didn’t know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610.

Detailed explanation-2: -The Moon is an astronomical body that orbits planet Earth and is Earth’s only permanent natural satellite.

Detailed explanation-3: -A satellite is an object that moves around a larger object. Earth is a satellite because it moves around the sun. The moon is a satellite because it moves around Earth. Earth and the moon are called “natural” satellites.

Detailed explanation-4: -The answer is no moons at all. That’s right, Venus (and the planet Mercury) are the only two planets that don’t have a single natural moon orbiting them.

Detailed explanation-5: -The Moon has no natural satellites itself. As far as astronomers are aware, none of the moons in the solar system have their own moons.

Detailed explanation-6: -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.
