Jumbo Jet-Size Asteroid 2010 WC9 Buzzes Earth Soon: See It Live Online Tonight

An asteroid the size of a jumbo jet is about to buzz Earth, and you can learn all about the historic close encounter in a webcast this evening (May 14).

The near-Earth asteroid 2010 WC9, which is thought to be between 125 feet and 390 feet (38 to 119 meters) wide, will get within 126,000 miles (203,000 kilometers) of Earth tomorrow evening (May 15) — about half the distance between our planet and the moon. It's rare for such a big space rock to get so close, astronomers have said.

To mark the occasion, the astronomy broadcasting service Slooh will host a live webcast tonight at 8 p.m. EDT (0000 GMT on May 15). You can also watch the webcast on Space.com, courtesy of Slooh.

This is another case where we discovered the asteroid, then lost it for several years, only to find it again just a week ago.  Which would seem to indicate that just because NASA may have discovered 98% of the NEOs larger than 1 km, it does not necessarily mean that they know where those NEOs are today.  Of the 17,785 NEOs (as of March 1, 2018) that NASA has discovered, I would be very interested in knowing the percentage of NEOs that NASA has lost since their discovery.  I would be willing to wager that it is a significant percentage.
