Asteroid orbit path comes close to Earth, left of center.
2013 continues to be the Year of the Asteroid Menace. Today a recently-discovered asteroid, 2013 LR6, will approach the Earth's orbit today and pass close by tomorrow. The 50 foot-wide rock will come closer than does the Moon, at about 68,000 miles (the Moon is at about 240,000 miles). That's close in NEO terms (Near Earth Objects).
Yahoo News has a good article explaining more about this event and a link to watch the approach LIVE: http://news.yahoo.com/asteroid-fly-within-moons-orbit-tomorrow-watch-live-153153909.html
From the SpaceRubble Command Bunker: We often hear that scientists have discovered such-and-such percent of the asteroids that could hit us. Yet rocks such as this one, the recent big one and the Chelyabinsk meteor hit prove that it's the ones you don't see coming that are the true danger to the Earth. And if they aren't seeing all of them, then we really don't have a number we can pin a percentage on, we only have a Wild-a** guess to go on, 'cause who in the heck knows everything that's out there in space!
