Asteroid — 2012 TC4 — is going to fly past the Earth at a distance of only 95,000 kilometers (59,000 miles), or one-quarter the Earth-moon distance. As far as near-misses go, that’s the outer edge of the bulls-eye!!!
This is not a Potentially Hazardous Asteroids (PHAs). Those are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
We need as many eyes out there!
