Pluto is the coldest planet of all, which is not surprising, because it is usually the farthest from the Sun. Inside, it is made up of ice and rock, and the planet has a thick layer of ice over the top.
Is it true? Pluto was named after a cartoon dog.
No. Pluto was the name of the Greek god of the underworld. Also, the first two letters of Pluto, ‘P’ and ‘L’ are the initials of Percival Lowell, who first predicted a planet beyond Neptune.
Who found Pluto’s moon?
An American called Jim Christy discovered Pluto’s moon in 1978. He called it Charon, which was his wife’s name, and also the name of the man who ferried people to the underworld in Ancient Greek mythology.
Is Pluto always farthest from the Sun?
Pluto is so far away from the Sun that it takes 248 years just to orbit it once! But Pluto’s orbit is a funny shape. For 20 years of its orbit, Pluto dips in closer to the Sun than Neptune. When this happens, Neptune is the farthest planet in the Solar System.
Amazing! Pluto is smaller than a country. Pluto is a tiny planet – the smallest in the Solar System. At 2,360 km across, it is smaller than the United States or Russia!
