(PhysOrg.com) -- Apostolos Christou and David Asher from the Armagh Observatory in Northern Ireland announced the discovery of an asteroid near Earth called Asteroid 2010 SO16 and their findings were published on arXiv.org. While finding near-Earth asteroids is not unusual, there is something quite rare about this particular asteroid in that it orbits the sun in what is referred to as a horseshoe orbit.
