Pluto:

Mike Brown: reduced the 9 planets to 8 planets

Among our planets Pluto was always different. Had the largest moon proportioned to its own size, had a egg shaped orbital.

Search for Pluto was started by Percival, and Clive Tombar. Some scientist argued then that Pluto was too small in size.

Smaller than our moon it was originally thought to me as large as Mars. It was just called a planet w/o further research

Because of its distance away from the sun Pluto was named after the roman under god.

Pluto 2.7 billion away from earth. Pluto Takes 248 years to Pluto to orbit the sun.

Pluto’s bright areas are made from three types of ice, and the dark areas are probably sillican rocks. It is 34 times further away from the sun than the earth is.

Pluto’s average temperature is -388 degrees. Pluto’s gravity is one fifteenth of the Earth.

Pluto has a large number of impact craters.

Why was Pluto kicked out of the Solar systems most exclusive club?

It has been a member of the Solar system for 70 years.

In 2005 Mike Brown found an object bigger than Pluto orbiting around the Sun with its own moon. He thought this was the 10th planet.
