Earth has always had two moons: The discovery of mysterious tiny asteroids which constantly circle our planet
When astronomers caught sight of a mysterious titanium white object circling the Earth in 2006, they assumed it was a spent rocket.
But it was actually a small asteroid captured by our gravitational field which rotated around the Earth until June 2007.
And a new study published yesterday by astrophysicists at Cornell claims this little moon was not an anomaly – these asteroids come and go so often it means our planet always has a temporary second moon.
Cornell University’s Mikael Granvik, Jeremie Vaubaillon and Robert Jedicke say they have calculated the population of ‘irregular natural satellites that are temporarily captured’ by Earth.
