asteroid orbits are often not circular and thus their distance to Earth changes. For example, on February 15 of 2013, Asteroid 2012 DA14 will cross very close to Earth (about 4000 miles) - so close that it will actually be lower than many of the satellites we use. read more

The distance between the Asteroid Belt and Earth varies considerably depending on where we measure to. Based on its average distance from the Sun, the distance between Earth and the closest edge of the Belt can be said to be between 1.2 to 2.2 AUs, or 179.5 and 329 million km (111.5 and 204.43 million mi). read more
