Astronomy

Most of the mass of the solar system is concentrated in the Sun, with its 1.99 × 10 33 grams. Together, all of the planets amount to 2.7 × 10 30 grams (i.e., about one-thousandth of the Sun''s mass), and Jupiter alone accounts for 71 percent of this amount. The solar system also contains five known objects of intermediate size classified as dwarf planets and a very large

Pluto

Pluto is a dwarf planet located in a distant region of our solar system beyond Neptune known as the Kuiper Belt. Pluto was long considered our ninth planet, but the International Astronomical Union reclassified Pluto as a dwarf planet in 2006.
