What do we know about asteroids? They can be very different in size, shape, and makeup. Some asteroids, like Ceres, have been reclassified as dwarf planets because of their composition. Ceres, unlike the asteroid Vesta which is dry and rocky, contains water-bearing minerals.

In this image of Vesta, taken by NASA's Dawn spacecraft just shortly before the beginning of high altitude mapping orbit, north is up and the upper right corner is to the northeast. The spacecraft's distance to Vesta's center is about 420 miles (680 kilometers). Recently, NASA released images that showed a mountain range on Vesta was three times as high as Mt. Everest.

This week, the North Jersey Astronomical Group’s monthly meeting will have Kevin Conod of the Newark Museum’s Dreyfuss Planetarium giving a lecture dubbed, “All About Asteroids.” Conod will discuss the history of asteroid discovery and the latest information about them from NASA’s Dawn spacecraft.

The free lecture will be held at Montclair State University’s Richardson Hall, Room 232, at 8 p.m. tomorrow, Wednesday, Oct. 12. Will we see you there?
