Synopsis >

When asteroid 1998 QE2 makes its closest approach to Earth on Friday, it will not be traveling alone: The massive space rock is hurtling through space accompanied by its own moon. It is not unheard of for an asteroid to have a moon, or satellite, accompanying it on its journey, but it is rare. Just 16% of asteroids that are 655 feet across or larger are part of a binary or triple system, according to the Jet Propulsion Laboratory in Pasadena.
