Two asteroids to whizz harmlessly past Earth
NASA says two small asteroids discovered just days ago will zip harmlessly past Earth on Wednesday, a double flyby that should be visible through a telescope.
The asteroids were discovered on Sunday by the NASA-funded Catalina Sky Survey in Arizona. The Minor Planet Center in Massachusetts, which tracks asteroids and comets, determined there was no chance of an Earth collision.
Asteroid 2010 RX30, thought to be 10 to 20 meters long, will pass within 248, 000 kilometers of Earth shortly before 3 a.m. PDT; (1000 GMT) Wednesday.
The second one, dubbed 2010 RF12, will fly by about 11 hours later at a distance of about 79, 000 kilometers. NASA says the second one is 6 to 14 meters long.
