Q:

What are some interesting facts about Pluto?

A:

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.

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.

  • Q:

    Does Pluto have craters?

    A:

    Pluto, a dwarf planet, is subject to impact from cosmic material, which is the cause of planetary "craters." Pluto, however, is not close enough to Earth for modern imaging techniques to specifically identify these craters. They are assumed to exist.

  • Q:

    When did Pluto become a dwarf planet?

    A:

    Pluto became a dwarf planet in 2006. Upon being stripped of its title as a planet, Pluto joined two other celestial bodies, called Eris and Ceres, in the category of dwarf planets. The decision to reclassify the former planet was made by the International Astronomical Union (IAU).

    What are some facts about Mars?

    A:

    Mars is 142 million miles from the Sun and takes 687 Earth days to complete one orbit around the sun, according to the National Aeronautics and Space Administration. The average surface temperature on Mars is -81 degrees Fahrenheit, and the small red planet has a much weaker gravitational pull than that of Earth. Mars also has 15 percent of the volume of Earth.

  • Q:

    Why is Pluto not a planet?

    A:

    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.
