Pluto is a dwarf planet in the area of the Kuiper belt, which is an area with many dwarf planets, according to the National Aeronautics and Space Administration (NASA). The dwarf planet is after Neptune in the planetary alignment, and it is the former ninth planet until reclassification in 2006, clarifies the Space Telescope Science Institute.Know More
Pluto is an icy planet with a solid core, explains NASA. Instead of a water-based ice, the frozen surface is primarily formed of methane and nitrogen. The mantle of Pluto, however, forms from ice made of water. Some of the surface ice melts when Pluto orbits close to the sun, releasing the methane and nitrogen into the air to create a temporary atmosphere. Once Pluto moves away from the sun, the gases refreeze. Pluto’s elliptical orbit places the dwarf planet on an incline as it orbits through the solar system. Pluto’s mass is relatively small to the planets in the solar system. It also has a low point of gravity. Pluto has five moons that orbit the planet.
It takes 248 Earth years for Pluto to make one revolution around the sun. Pluto’s largest moon, Charon, takes more than six days to orbit once around Pluto. Charon is roughly half the size of Pluto.Learn more about Planets

In 2006, the International Astronomical Union changed Pluto's classification from a planet to a dwarf planet because the planet has not cleared its orbit of other objects. When a planet clears its orbit, all other objects on the orbital path are either drawn into the planet's gravitational pull or flung away from it and out of the orbit.Full Answer >
The most popular theory regarding lunar formation is that a Mars-sized planetoid slammed into the Earth and flung molten debris into orbit around 40 million years after the solar system was created, according to scientists at the National Aeronautics and Space Administration (NASA). This is called the giant impact theory.Full Answer >
