The first asteroid found is 1 Ceres, which was founded in 1801 by Giuseppe Piazzi. At that time, the asteroid known as a planetoid.
It's as much as hundreds of thousands of asteroids in our solar system discovered, and new discoveries are now an average of 5000 pieces per month. On August 27, 2006, of a total of 339,376 registered small planet, of whom 136,563 have orbits known enough so that it can be given permanent official numbers. Among these planets, 13,350 [1] has an official name (trivia: about 650 of these names requires identification). Lowest number but a small planet that is not named (3360) 1981 VA; minor planet named for the top number (except the dwarf planet 136199 Eris and Pluto 134,340) is 129,342 Ependes [2].
Now estimated that the asteroid with a diameter of more than 1 km in the solar system solar systems totaling between 1.1 to 1.9 million [3]. Largest asteroid dapam inner solar system is 1 Ceres, with a diameter of 900-1000 km. Two asteroid belts inner solar system that is 2 Pallas and 4 Vesta; both have a diameter of ~ 500 km. Vesta is the asteroid main belt, most kadnag sometimes visible to the naked eye (in some fairly rare events, asteroid close to earth can be seen without technical assistance; see Apophis 99,942).
The mass of the asteroid Main Belt is estimated at 3.0-3.6 × 1021 kg [4] [5], or roughly 4% of the mass of the moon. From all this, a mass of 1 Ceres 0.95 × 1021 kg, 32% of the total. Then populous asteroid, 4 Vesta (9%), 2 Pallas (7%), and 10 Hygiea (3%), making this estimate to 51%; three onwards, 511 Davida (1.2%), 704 Interamnia (1.0%), and 3 Juno (0.9%), only add 3% of the mass totalna. The number next asteroid is increasing exponentially, although the mass of each fall. It is said that the asteroid Ida has a satellite named Dactyl
