Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
What is the name of our galaxy?
Astronomy > The Milky Way Galaxy. Did you know that our star, the Sun, is just one of hundreds of billions of stars swirling within an enormous cosmic place called the Milky Way Galaxy? The Milky Way is a huge collection of stars, dust and gas.
