An asteroid 2009 BD, the 23-foot-long (7-meter) space rock, came within 215,000 miles (346,000 kilometers) of Earth at around 8:51 p.m. EDT (0051 GMT on June 2). The moon’s average distance from us is about 239,000 miles (385,000 km).According to scientists asteroid 2009 BD is a small object, only 7 meters, which doesn’t represent any threats.Scientists think that after the close pass, asteroid 2009 BD didn’t recede into the depths of space, it will remain within 10 lunar distances of us for the next month or so.That’s because 2009 BD is no ordinary asteroid. It’s what astronomers call a “co-orbital object,” meaning its path around the sun nearly parallels that of Earth. According to scientists space rocks fall into Earth’s atmosphere every month or so, but most of them burn up before reaching the ground.
