Recently discovered by diligent astronomers at the Mount Lemmon Sky Survey in Tucson, Arizona, the two asteroids are approaching on different trajectories and will shoot past the Earth some 11 hours apart.
According to a Space.com report, scientists have said neither chunk of galactic detritus poses an impact threat to our planet but they will both pass at a distance far less than that of the moon.
The larger asteroid, which is known as 2010 RX30 and is between 33 and 72 feet in size, will be the first to arrive and is likely to zoom by at a distance of 154,000 miles (248,000 km) at around 5:51 a.m. ET, according to NASA痴 Jet Propulsion Laboratory.
The smaller of the two asteroids, which is known as 2010 RF12 and is between 19 and 43 feet in size, is expected to pass at a distance of around 49,000 miles (79,000 km) at 5:12 p.m. ET.
The moon average distance from Earth is approximately 238,600 miles (384,000 km). However, despite the apparent close proximity of the asteroids neither will be visible to the naked eye.
Both chunks of space rock were initially spotted on Sunday, at which point their approaches were reviewed and preliminary orbits determined by the Minor Planet Center in Cambridge, Massachusetts.
