Two close calls for Earth as asteroids brush by Earth this week

Two close calls for Earth as asteroids brush by Earth this week

Two asteroids will pass within the Moon’s distance from Earth on Wednesday, Sept. 8. and should be visible with moderate-sized amateur telescopes, say scientists . But no need to fret, neither will hit Earth.  But the numbers will raise eyebrows I think… RX30 is estimated to be 32 to 65 feet in size and will pass within 154,000 miles of Earth at 5:51 a.m. EDT Wednesday. The second object, RF12, estimated to be 20 to 46 feet in size, will pass within 49,000 miles at 5:12 p.m. EDT.

Wired.com is reporting “According to NASA’s Near Earth Object impact risk tables, the odds that 2010 RF12 will hit the Earth are about 1 in 50, and the odds of an impact with 2010 RX30 are less than 1 in 1000. Both objects are too small to do much damage even if they were to smack into the Earth; much of their rocky mass probably wouldn’t survive the trip through Earth’s atmosphere. Because of their small sizes, they won’t be visible with the naked eye. But they should be bright enough to observe with a modest-sized telescope…”
