There are dozens of moons around the giant planets. Neptune is the smallest gas giant. Neptune has 13 known moons, the largest of which is Triton. However, it is twice as far from Earth as Jupiter, and from Saturn the Sun appears about 10 times smaller than how we see it from Earth. It is believed that the planet core is comprised of rock and nickel-iron alloy. Uranus may also have several Trojan asteroids (asteroids in the same orbit as the planet); the first was found in 2013. The term "gas giant" was originally synonymous with "giant planet", but in the 1990s it became known that Uranus and Neptuneare really a distinct class of giant planet, being composed mainly of heavier volatile substances (which are referred to as "ices"). This likely explains why they are smaller than those two planets. At the time they conceived of this, there was no real info about the amount of amino acids that might exist in the atmospheres of planets like Saturn and Jupiter. Actually, it no longer is. These four large planets, also called jovian planets after Jupiter, reside in the outer part of the solar system past the orbits of Mars and the asteroid belt. The planet is mostly made of hydrogen and helium surrounding a dense core of rocks and ice, with most of its bulk likely made up of liquid metallic hydrogen, which creates a huge magnetic field.
