View Full Version : Hubble's Accidental Asteroid Discovery

SUMMARY: Although they were using the Hubble Space Telescope to analyze the Sagittarius dwarf galaxy, an international team of astronomers were also able to discover a new asteroid that happened to drift through Hubble's field of view. The asteroid is 270 million km (169 million miles) from Earth, which probably puts it into the main asteroid belt, between the orbits of Mars and Jupiter - it's only 2.4 km (1.5 miles) across. The asteroid's path is wavy because Hubble was orbiting the Earth as it took a series of long exposures, and the gaps come from times that Hubble's shutter was closed.
