Asteroid Annefrank
Credit: STARDUST Team, JPL, NASA

Explanation: NASA's interplanetary probe STARDUST, on its way to Comet Wild 2 in January 2004, passed asteroid 5535 Annefrank earlier this month. Annefrank, named for a holocaust victim who kept a famous diary, is a member of the main asteroid belt between Mars and Jupiter. Just prior to closest approach at about 3300 km distant, the robot spacecraft took the above picture. Although images obtained were not detailed enough to resolve much of the asteroid's surface, the size, reflectivity, and general shape of the asteroid were recorded. At 6 kilometers across, asteroid Annefrank turned out to be larger -- and darker -- than expected.

Astronomy Fun Fact:

There are several hundred thousand asteroids that have been catalogued and given names. Thousands more are discovered each year. Total mass of all known asteroids is less than that of the Moon.

Most asteroids are in one of several groups. Many are in the main asteroid belt. Others are Near-Earth asteroids. Still others orbit 60 degrees ahead and behind Jupiter. This list is by no means complete.

Ever wonder about the moons of Mars? They seem to be captured asteroids, but their orbits seem almost artificial. Got to wonder. Also, Phobos would be excellent for the first manned Mars base.
