Pluto is the ninth planet from our sun in the solar system. Pluto was discovered as the result of a telescopic search inaugurated in 1905 by the American astronomer, Percival Lowell. It is an outer planet because it is past the asteroid belt that divides Jupiter and Mars. Because of Pluto's irregular orbit, sometimes its position in the solar system is the eighth planet, in front of Neptune, as the diagram below shows:
Pluto is the very small planet at the edge of the solar system. No telescope has ever seen Pluto or its moon in detail; they can only guess what the atmosphere is made of. We believe it is a rocky planet probably covered with ice and frozen methane. The next planet towards the sun is Neptune. From 1990-1999, Pluto and Neptune switched places in the solar system.
Other interesting facts about Planet Pluto
What would it be like to live on the surface of Pluto? One possibility is that you are standing on a rocky ground covered in ice where it snows methane flakes for 228 years of its 248 years of orbit. From Pluto's surface, Charon looks like 7x the diameter of our moon. Charon doesn't rise or set like our moon because Pluto always faces Charon. Pluto is smaller than Earth's moon. That's small. But, Charon is half the size of Pluto. Charon orbits Pluto. Charon was discovered in 1979,and like Pluto, it is icy cold. Some scientists believe that Pluto and Charon may be made completely of ice! A year on Pluto lasts 248 earth years and one day lasts 6 days, 9 hours and 18 minutes. The temperature is probably -360 degrees Fahrenheit, which is colder than any place on earth!
Did you know?...
To Pluto, the sun is just a bright star!
Pluto has a tiny moon called Charon, which is about half its size!
No one can live on Pluto because most of the atmosphere is methane gas! HELP!!!!!
Pluto is smaller than our moon!!
Pluto is 3.6 billion miles from the sun!!!
