In 2001, the Near Earth Asteroid Rendezvous spacecraft landed on the asteroid Eros. The data it sent back to NASA shows that the asteroid has an unusual sense of gravity. “In this view, a map of gravitational topography has been painted onto a shape model. Red areas are uphill and blue areas are downhill,” writes NASA. “A ball dropped onto one of the red spots would try to roll across the nearest green area to the nearest blue area.”
Scientists believe that the asteroid belt between Jupiter and Mars may have been a planet that was unable to form because of Jupiter’s strong gravitational field. The asteroid may have been a planetoid that formed at the beginning of the solar system, but then broke apart after colliding with other asteroids. Ultimately, Eros just may have been the bearer of bad luck.
