How many planets orbit the sun?


assistant
For many years astronomers stated that there were 9 planets that orbited the Sun. In 2006 the 9th planet and furthest from the Sun, Pluto, was demoted from a planet to a dwarf planet. Technically there are now 8 planets and 1 dwarf planet that orbit the Sun.
