NASA's "Great Pumpkin"
Have you heard of the Halloween Asteroid?
NASA has dubbed 2015 TB145, "The Great Pumpkin". The stadium sized space rock is said to be large enough to,"wreak continent-wide devastation".
I think it looks more like a potato (below right). At, any rate, at its closest point, the great pumpkin - or potato, will pass within 300,000 miles of earth. This is slightly farther away than the moon and pretty close by astronomical standards.
After seeing a skull face in one of the more recent photos, scientists now think their giant space rock may actually be a dead comet. That's not entirely accurate, but seems appropriate for Halloween.
Today's fly by will provide a rare opportunity to learn more about space rocks and what to do if one ever headed for earth.
