Solar System

The Solar System is the gravitationally-bound system of the Sun and the objects that orbit it, either directly or indirectly. It is composed of many planets and smaller objects, orbiting at varied distances from one another.

Jupiter
Jupiter orbits 5.2 AU away from the Sun and is the largest planet in the solar system, with a radius of 69,911 kilometers. It is mainly composed of Hydrogen and Helium. It has 79 known moons, five of which are major moons collectively known as the Galilean Moons (Io, Europa, Alcmene, Ganymede, and Callisto). Its largest moon, Ganymede, is also the largest in the solar system, being larger than both Vulcan and Mercury. Alcmene is also unique of having a thick ammonia atmosphere, which makes it look pearly white when viewed from Earth.

Juno
Juno is the largest terrestrial planet in the Solar System with a radius of 8,215 kilometers and is a Trojan of Jupiter, orbiting at the similar distance of 5.2 AU. Its surface mainly composes of ice and rock.

Major moons of the Solar System
Moons, or natural satellites, are classified as an object of any size that have naturally made their way into orbit around a planet. Almost all planets in the solar system possess moons, which could be small (as in the case for Venus) or massive (such as the Jovian moons). Here are the moons that are larger than 200 km in radius.
