Discovered Before Seen
Pluto is the coldest planet in the solar system as it is the furthest
away. It is also the smallest; some of the other, larger planets have
moons the size of Pluto. As it is so far away, it takes 249 Earth years
just to complete one of its own years.
Pluto is so far away from Earth that it was not discovered until the
1930's.
Even with the most powerful telescopes
- it is still difficult to see this lonely planet.
