Is Pluto still part of the Solar system?

1 Orbit of Sun 90,465 Days 1 Rotation 6 Days 9 Hours Mass 0.02% of Earth Volume 1% of Earth Escape Velocity 15,449 km/h (9,600 mph) Distance From Sun 5,869 million kilometers (3,647 million miles) Avg Temperature -234° C (-390° F) Atmosphere Methane, Nitrogen Diameter 2,390 kilometers (1,485 miles)

Did you know? Pluto revolves around the Sun in an orbit that is not exactly circular like the rest of the planets. Rather, Plutos orbit is more of an oval or egg shape. Because of this, Pluto will orbit inside of Neptunes orbit, which makes Pluto closer to the Sun than Neptune at times. Also, its orbit does not lie flat in the same plane as the rest of the planets. Plutos orbit is tilted so it orbits above and below the other planets orbits in our Solar System.

Pluto Scientists believe Pluto is about two-thirds rock and one-third water ice. There might actually be more water on Pluto than on Earth. Like Neptune, Pluto was discovered through mathematical predictions instead of observation.rockwaterEarth In 1906 Percival Lowell started the search for the planet X. He believed that another planet must exist that he could find with mathematics. Unfortunately, he died before finding Pluto. Pluto wasnt discovered until 1930 by Clyde Tombaugh. He was working at the observatory of Percival Lowell and reviewing his previous work. Clyde Tombaugh discovered the planet after a year of searching.

Pluto Means Pluto is the Roman god of the underworld. He is the brother of Neptune and Jupiter.RomanJupiter In Greek mythology, hes counterpart is Hades.Greek Pluto was given its name by an 11- year-old girl! Her name was Venetia Burney, who lived in Oxford, England. When they discovered the planet in 1930, she said they should name it after the Roman god of the underworld. Venetias grandfather sent this suggestion to the Lowell Observatory. And thats how Pluto got its name.

Because Pluto is so small you would be very light if you visited. If you weigh 70 pounds (32 kg) on Earth, you would only weigh 4 pounds (2.5 kg) on Pluto. The planets gravity gravity is super weak ! How much would you weigh on Pluto?

Pluto is smaller than 7 of the moons in the Solar System. It is about two-thirds smaller than Earths moon. Because it is so small, many scientists dont consider it a planet at all. In 1999, a group of scientists attempted to re-classify Pluto as a comet.Earths mooncomet On August 24, 2006, Plutos status was officially changed from planet to dwarf planet. Pluto had previously been a planet for 75 years. For decades, children were taught in school that there are nine planets in our Solar System. However, with this change, there are now only eight official planets.dwarf planetplanets The Dwarf Planet

Even More Dwarf Planets What brought about this new status was the discovery of other dwarf planets. Beginning in 1992, scientists discovered other dwarf planets orbiting in the same area as Pluto. Today scientists have discovered more than a thousand objects in this area. With these discoveries, there was a new category created called the plutoids. Pluto is the largest of the dwarf planets. These plutoids are in an area that scientists have named the Kuiper Belt. This belt likely consists of mostly icy materials. The discovery of Eris, another dwarf planet sparked the discussion, what makes a planet a planet?Kuiper Belt

This planet has 5 moons. The largest is Charon. Charon is only slightly smaller than its parent Pluto. For this reason, Pluto and Charon are often called a double planet system. The Earth and its moon, Luna, are sometimes considered double planets. Plutos moons are Hydra, Styx, Kerberos and Nix.Plutos moons Moons

Plutos moons, many were just discovered in the past 18 years.
