Different moons of Saturn and their description

moons of saturn

Introduction

Saturn is known as the “moon king” of the solar system because it has a total of 82 moons. Out of these 82 moons, 53 were named and 29 were are waiting for confirmation. They are unconfirmed because of the little information about their structure and composition and other things. If all of these moons get confirmed, Saturn will have 82 moons. And that’s not counting Saturn’s beautiful rings. The moons of  Saturn thus describe below.

Different moons of Saturn with their interesting facts

1. Titan

This moon of Saturn is the most famous moon and we all know about this natural satellite. It is the largest moon of the Saturn and the second-largest moon in our entire solar system. Size is even bigger than that of Mercury. Titan is the only place other than the earth that holds fluids in the form of rivers, lakes, and oceans underneath it.

2. Hyperion

It is the largest moon in the solar system. It is a potato-shaped satellite hence is nonspherical in its structure. Due to its irregular structure, Hyperion constantly changes its rotation path thus creates chaos with its nearing satellites. The temperature of this moon is about -180°C. It travels around the Saturn in an eccentric orbit with an average distance of 932,637 miles. This satellite is mainly composed of ice and carbon dioxide.

3. Rhea

It is the second-largest moon of Saturn. Made up of mainly rocks and ice. this is the only satellite of Saturn with oxygen in the atmosphere. Because of uneven rocks, it is the most heavily cratered satellite in our solar system. 949 miles in diameter, orbits farther from the planet, averaging 327,490 miles away.

Apart from these 62 moons, more than 20 satellites have been discovered in Saturn. These satellites are discovered in October 2019. Saturn has the largest number of moons in the solar system (2) & (5).

Since Saturn does not have a real surface, but rather a rotating fluid, we know it is not conducive to life. Saturn’s moons have the inner oceans of Titan and Enceladus, respectively that could possibly contain life. Saturn’s wind is the second-fastest among the planets in the solar system after Neptune (1).
