But after its orbit was better determined it was clear that it was not a comet but more like a small planet. Piazzi named it Ceres, after the Sicilian goddess of grain. Three other small bodies were discovered in the next few years (Pallas, Vesta, and Juno). By the end of the 19th century there were several hundred. Several hundred thousand asteroids have been discovered and given provisional designations so far. Thousands more are discovered each year. There are undoubtedly hundreds of thousands more that are too small to be seen from the Earth . There are 26 known asteroids larger than 200 km in diameter. Our census of the largest ones is now fairly complete: we probab Read More Go to Site Near Earth Asteroid Rendezvous Mission Votes:0 NEAR Shoemaker's Final Images Descent to Eros information February 14 Press Conference slides NEAR Shoemaker's Descent Movies Image of the Day 2001 Mar 01 Gamma-Ray Readings from Eros Image of the Day Archive --> Press Release (Feb 28) The End of an Asteroidal Adventure: NEAR Shoemaker Phones Home for the Last Time [ More ] Press Release Archive --> Science Update On Monday, 12 February 2001, the NEAR spacecraft touched down on asteroid Eros, after transmitting 69 close-up images of the surface during its final descent.

More than 4,700 near-Earth asteroids have been found to date, a fraction of the suspected total population. An estimated 700 of these are large enough to produce global disaster if they were to hit Earth. Make an impact--support our NEO Fund today. A mountain of rock and iron is hurtling toward Earth-- your help is needed now. Like an oncoming train, the asteroid Apophis is headed toward Earth. In 2029, it will come closer to our surface than some of our own orbiting weather satellites. If it shifts just a few hundred kilometers--a fraction of a degree--Apophis could very well return in 2036 to slam into Earth and create widespread devastation.
