Planetary scientists weren't remotely expecting the 62-foot-wide Chelyabinsk fireball to shoot across Russian skies in February -- they'd had their eyes peeled on a much bigger target that missed the Earth by a decent margin, the asteroid 2012 DA14. But this relatively modest, unseen space rock caused a shock wave that shattered countless windows in the city and injured more than a thousand people. It was the largest asteroid impact on land in more than a century. Researchers are now saying that such impacts, from relatively small asteroids just tens of yards long, might be 10 times more common than we'd thought.

ST. PETERSBURG, Russia -- Ukrainian astronomers say an asteroid might collide with Earth in a couple of decades, a Russian news service reported Thursday. Space watchers from the observatory in the Crimean peninsula said they discovered an asteroid about 1,345 feet in diameter, which they call 2013 TV135, that is approaching Earth at a potentially dangerous trajectory, RIA Novosti said. The astronomers calculated the date of a potential collision as Aug. 26, 2032, the news service said, but they acknowledged the odds of an impact as 1 in 63,000.

Having trouble getting excited about NASA's planned mission to redirect an asteroid? Maybe William Gerstenmaier can help. "Turn off your logical side and turn on your touchy-feely side, the one you almost never use," Gerstenmaier, associate administrator for NASA's Human Exploration and Operations Directorate, told attendees of an aeronautics and astronautics conference Wednesday in San Diego. "Then jump up and down and do some break-dancing. We're going to grab a space rock and we're going to move it!"

It's 1.7 miles long. Its surface is covered in a sooty black substance similar to the gunk at the bottom of a barbecue. If it impacted Earth it would probably result in global extinction. Good thing it is just making a flyby. Asteroid 1998 QE2 will make its closest pass to Earth on May 31 at 1:59 p.m. PDT. Scientists are not sure where this unusually large space rock, which was discovered 15 years ago, originated from. But the mysterious sooty substance on its surface could indicate it may be the result of a comet that flew too close to the sun, said Amy Mainzer, who tracks near-Earth objects at Jet Propulsion Laboratory in La Cañada Flintridge . It might also have leaked out of the asteroid belt between the orbits of Mars and Jupiter, she said.

An asteroid roughly the size of a football field will make its closest approach to Earth on Monday, and you can watch it zip through the sky, live, right here. A live feed of asteroid 2013 NE19, provided by Slooh.com , will start at 6 p.m. PDT. Asteroid quiz: Test your space rock knowledge Asteroid 2013 NE19 was discovered less than a week ago by the Pan-STARRS telescope in Haleakala, Hawaii. Scientists estimate it is 200 to 400 feet long and is hurtling through space at the speed of 64,000 miles per hour.

A massive asteroid the length of three football fields will make its closest approach to Earth tonight, and you can watch it fly by live, right here. Beginning at 6 p.m. PST, the astronomy website Slooh.com will provide a live video feed of the asteroid from a telescope in the Canary Islands. The free show will last about an hour and will be visible in the video box above. Asteroid the length of 3 football fields eludes sky-watchers The asteroid is known as 2000 EM26, and although it is big, it poses no threat to Earth.
