Abstract: | The dynamical evolution of an asteroid with orbital elements strikingly similar to the Earth is analysed. The object, 1991
VG, was discovered by the Spacewatch telescope during a particular encounter with the planet. 1991 VG experienced a temporary
satellite capture by the Earth, a phenomena that is recurrent in its dynamical history. The possible origin of this puzzling
object is discussed, including the suggestion that 1991 VG could be a piece of lunar ejecta after a great impact.
