KUIPER BELT OBJECTS Rosemary R.. What Is The Kuiper Belt?  The Kuiper Belt is a disc-shaped region of icy objects beyond the orbit of Neptune.  Found.

Initial attempts to produce orbit for Uranus unsuccessful 1821: Bouvard produces orbit based on contemporary observations includes gravitational influences.

Planet Searching After Uranus and Neptune, some began searching for yet another planet, among them was P. Lowell from Search resumed in 1929.

February 18, 1930 Pluto discovered by Clyde Tombaugh. It was the first planet discovered by an American. Tombaugh was hired to search for proof of theories.

The known Universe consists of only 8 bodies: Earth, Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn. Earth is thought to be the centre of the Universe.

The Sun The Sun is a star. The Sun is a star. It is 4,500 million years old It is 4,500 million years old It takes 8 minutes for its light to reach.
