I was kinda right.

Last week I was wondering if the QE2 asteroid that was passing by Earth my be trailing some debris that could stray into our atmosphere.

It really wasn’t possible due to the great distance away from us that QE2 passed, but it was a fun speculation.  Actually, it wasn’t even that much of a speculation.  According to NASA about 16 percent of asteroids are binary or triple systems.   Well now it turns out that QE2 has its own moon…sort of.

Radar images take during the flyby reveal that QE2’s moon is about 2,000 feet (600 meters) wide. If moon of QE2 (must give it a better name) hit the Earth, it would be bad day.

But, evidently, you must be this big to destroy the Earth.

The next pass of the QE2 and moon of QE2 (really, really must get better name!) July 12, 2028 it will be much farther away from the Earth at 45 million miles.

At least this has the major governments interested in early detection.  Had QE2 been on a collision course, the only thing we could have done is duck and cover.
