Pluto was discovered in 1930 by an astronomer from the United States.
Pluto was known as the smallest planet in the solar system and the ninth planet
from the sun.
In
2006 NASA said Pluto is no longer a planet in the Solar System because there
appeared to be a bunch of other big rocks just like Pluto out beyond the eighth
planet (Neptune), all considered too small to be called a planet.
Eight
years later, and Pluto got a chance to reclaim its planetary spot in our solar
system. Standing behind the logic that “Even though a dwarf
fruit tree is still a small fruit tree, and a dwarf hamster is still a small
hamster,” The
Harvard-Smithsonian Center for Astrophysics decided to revisit
the IAU’s ruling by hosting a discussion on the definition of a planet.
So there you
have it. Pluto is back in
Did
you know: In 2006, NASA launched the first mission to Pluto. It is called New
Horizons. New Horizons is a spacecraft that is going to the edge of the solar
system. The spacecraft is about the size of a piano. It will take nine years to
reach Pluto. In 2015, New Horizons will arrive at Pluto. The mission will spend
more than five months studying Pluto and its moons
