Neptune’s Fun Facts Neptune’s Moons A day on Neptune Neptune has actually has thirteen (known) moons. I say known because the Voyager 2 is the only thing that has taken pictures and collected information about this strange yet enchanting blue planet ! In fact Neptune like it’s twin Uranus has an atmosphere composed of hydrogen, helium, methane, and ammonia. A day on Neptune is known to be sixteen hours long. And as you by now well know a day on Earth is twenty-four hours long!
Additional Areas of Neptune Neptune is one of four planets in our Solar System with planetary rings. Neptune was not discovered until 1846 and its rings were only discovered definitively in 1989 by the Voyager 2 probe. Although the rings were not discovered until the late 1900’s, William Lassell who discovered Titan recorded that he had observed a ring. However, this was never confirmed. The first ring was actually discovered in 1968, but scientists were unable to determine if it was a complete ring. The Voyager’s evidence was the definitive proof for the existence of the rings.
Need to-knows Is Neptune a Gas Giant Distance From The Sun Well, yes Neptune is a gas giant, also called a "Jovian" planet, along with Jupiter, Saturn, and Uranus. The terrestrial planets in our solar system are Mercury, Venus, Earth, and Mars. Gas giants have outer layers of molecular hydrogen, helium, and metallic hydrogen and possibly a solid inner core. Neptune’s distance from the Sun is 4.5 billion km; more specifically, it’s 4,503,443,661 km. If you’re still using the Imperial system, that’s the same as 2.8 billion miles But this number is actually an average. Like all of the planets in the Solar System, Neptune follows an elliptical orbit around the Sun, so it’s sometimes closer and sometimes further than this average number.
Neptune’s size in diameter The diameter of Neptune is approximately 49,500 km. This makes Neptune the 4th largest planet in the Solar System, after Jupiter, Saturn and Uranus. I say approximately because the diameter of Neptune changes depending on where you measure it. Neptune is rotating on its axis, completing a full day once every 16 hours or so. This rapid rotation flattens Neptune out slightly so that the diameter measured from pole to pole is less than the equatorial diameter.
The End Hey, dude nice name!
