Is Pluto a planet?

No, Pluto is the largest known dwarf planet. Dwarf planets are nearly round objects that orbit the Sun, but have not cleared the neighborhood around their orbit. Pluto’s home is the Kuiper Belt – a region beyond Neptune in which millions of icy bodies orbit the Sun.

Interesting Facts
  • Pluto is on average 3.7 billion miles from the Sun.
  • Pluto is only 1,400 miles wide. That is the equivalent of St. Louis, MO to Salt Lake City, Utah!
  • Pluto is 375 to 400 degrees below zero Fahrenheit.
  • You would weigh approximately 15x less on Pluto than on Earth.
