Mystery Object Orbits Earth

"Could it be an alien spaceship? 'If it is,' says Chodas, 'the aliens aren't good pilots. J002E3 is in a chaotic orbit. It loops around Earth once every 48 days or so, coming as close to our planet as the Moon and ranging as far away as two lunar distances.' There's no evidence that the speck is moving under its own power. The orbit is constantly changing because of gravitational perturbations by the Sun and Moon.

At first Yeung and others thought J002E3 might be a small asteroid--a reasonable guess. The object is as bright as a 30m-wide space rock and it's moving about as fast as an asteroid should move. Mars and Jupiter have captured asteroid moons before; perhaps Earth had done the same."

I, for one, welcome our new erratic orbital overlords.
