Two asteroids to pass near Earth within Moon distance

Two asteroids will approach the Earth and will pass within a shorter range than the Moon, on Wednesday, 8 September 2010. The two asteroids with unrelated orbits will travel around by almost 11 hours apart from each other and will not be visible for the bare eye. Instead both can be observed with medium-sized amateur telescopes at the closest approach to Earth. The larger asteroid 2010 RX30 is estimated to have between 10 to 20 meters in size and is expected to be the first to pass nearby at about 248000 km from Earth (0.6 lunar distances) at 2:51 a.m PDT (5:51 am EDT). The smaller asteroid 2010 RF12 with a size between 6 to 14 meters will pass within just 0.2 lunar distances (79000 km) and is expected to arrive at 2:12 p.m PDT (5:12 p.m EDT). The orbits of the two objects are still higher than the geostationary (geosynchronous) orbits of the communication satellites which lie at 36000 km above the Earth.
