“Asteroid 2005 YU55 -like” object collides with Earth in a cosmic lightshow
Source: Yahoo News and Space.com
“Asteroid 2005 YU55’s pass by Earth will be closest to date by an object this large that we know about in advance. A smaller asteroid, called 2011 CQ1, actually came closer to Earth without hitting – a record-setting approach to within 3,400 miles (5,471 kilometers) — but it was not seen in advance.
The asteroid’s near-Earth flyby is also the first since 1976 that astronomers have known about in advance for such a large object. The next known flyby with a big space rock will occur in 2028, NASA scientists said.”
Perhaps the last line of that quote should read:
The next known flyby with a big space rock will occur in 2028, that is of course, if we see it, unlike CQ1 and the many more that we just don’t know about.
If you believe that is fantasy and we have the technology to see these space rocks, consider the fact that Asteroids are named for the year they were discovered. That means: 2005 YU55 we’ve known about for about 6 years. 2011 CQ1 was only discovered this year and only after it passed near our orbit.
