15. Does Eros have gravity? Gravity on Eros is weak, but it has enough pull to hold the NEAR Shoemaker spacecraft in orbit. Depending on where they stood on Eros, a person who weighed 200 pounds (90 kilograms) on Earth would weigh about two ounces on the asteroid. A rock tossed from the asteroid’s surface at 22 miles an hour could escape into space. A basketball player with a 36-inch vertical leap could jump about a mile on Eros – and risk putting himself in orbit! Surface gravity depends on the distance from a spot on the surface to the center of a body’s mass. The surface gravity on Eros varies a lot, since it is not a sphere but an elongated peanut-shaped (or potato-shaped, or shoe-shaped) object. 20. How close will NEAR Shoemaker get to Eros? NEAR Shoemaker is traveling at various distances around Eros. All told it will spend more than 100 days orbiting 31 miles (about 50 kilometers) from the center of Eros; at other times its orbit will extend to about 200 miles (320 kilometers). A low-altitude pass on Oct. 26, 2000, brought it to within 3 miles (about 5.3 kilometers) of the surface, before it headed back out to 125 miles (200 kilometers) for global observations. In mid-December 2000 it will descend to 22 miles (35 kilometers) and operate from that distance (or closer) for the rest of the mission. near.jhuapl.edu It's shape must give it a gravitational pull that varies...wouldn't you think? They must have to correct the orbit from time to time. o~~~ O
