Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.””

What will Planet 9 be called?

Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃.”

What is Earth’s full name?

“It is a common misconception that “Terra” is the internationally-recognized scientific name of the planet, but in reality Earth does not have an official international name. The standard English name of the planet, including in science, is “Earth”.”

Can a galaxy have two suns?

“Although the solar system has only one sun, most stars like Earth’s sun are binaries— two stars orbiting each other as a pair. Increasingly, astronomers are discovering planetary systems with twin suns (like Luke Skywalker’s fictional home planet Tatooine in “Star Wars”).”
