NASA: 1,000 Near-Earth Objects Larger than One Kilometer Sighted



Near-Earth objects (NEOs) are asteroids and comets that can approach the Earth's orbital distance to within about 28 million miles (45 million kilometers). They range in size from as small as a few feet to as large as 25 miles (41 kilometers) for the largest near-Earth asteroid, 1036 Ganymed. More than 10,000 asteroids and comets that can pass near Earth have now been discovered. The 10,000th near-Earth object, asteroid 2013 MZ5, was first detected on the night of June 18, 2013, by the Pan-STARRS-1 telescope, located on the 10,000-foot (3,000-meter) summit of the Haleakala crater on Maui.









Waiting for Comet ISON Here's One Of The BEST Photos ~ Here's the Predicted Path~



Comet ISON as captured by the Hubble Space Telescope Image via NASA, ESA, and the Hubble Heritage Team (STScI/AURA) Learn more about this image, from HubbleSite When it returns to our sky in late August, Comet ISON’s brightness will indicate whether the comet will be spectacular in late 2013, or not. Discovered in 2012, Comet C/2012 S1 (ISON) can’t be seen from Earth right now. Astronomers are waiting for Comet ISON to become viewable again in late August. Its brightness when it returns will indicate whether this comet will become a striking object, visible to the eye alone, by late 2013 – or not!
