Sun’s Heat Pushes Asteroids Out of their Orbit

Because of their irregular shapes, asteroids are warmed unevenly by the Sun. This force, called the ‘Yarkovsky effect’ is thought to slowly push asteroids out of their regular main-belt orbit. Astronomers believe that some of these strays are picked up by Mars’ gravity and hurled into Earth-crossing orbits.
