Jeff  Lchat, age 10, of Muncie, Ind., for his question:

Which is the biggest meteorite found?

In New York's Museum of Natural History there is a monster meteorite that weighs 362 tons. It is taller than you are and bulky enough to fill a small log cabin. This famous meteorite of blackish iron was found in Greenland and brought back by Captain Peary, the famous polar explorer. An iron meteorite estimated to wiegh 50 tons rests in Southwest Africa. Monsters nearly as big as this one have been found, also.

However, the biggest meteorites do not land in a solid lump. They tend to shatter on or near the ground. The shuddering impact scatters the fragments far and wide and digs a deep hole into the earth. In the remote past, such a whopping meteorite fell in Arizona.  It dug a deep crater more than a mile wide. Fragments of several hundred pounds were found near by.
