Asteroid to pass close to the Earth on the night of July 2-3
Those with an 8" telescope or greater should be able to see Asteroid 2004 XP14 as it passes within 430,000 KM (268,000 miles) of the Earth. At close approach the comet will brighten from 11th magnitude (it's normally much fainter) and be within reach of amateur telescopes.
As it nears the Earth the asteroid will pass with a velocity of 17 kilometers per second. From your perspective on Earth, you will see 2004 XP14 moving at about 7-8 degrees per hour against the background stars.
Closest approach to Earth occurs on July 3 at 12:52 am EDT.
