Incoming Asteroid! Not to Worry.

Here comes asteroid 2012 TC4. Despite a number of internet sites  talking about TC4 as if it is going to hit Earth the asteroid is going to safely pass by. Don’t buy into the doom-mongers click-bait.

Asteroid 2012 TC4 will flyby rather close to be sure.  On 12 October at 05:41 UT / 01:41 ET the asteroid will pass just 50,000 km / 31,000 miles or roughly 30 percent further away than our geosynchronous satellites.

2012 TC4 is about 15 meters / 50 ft and has a period of 1.67 years.  This time around it is going to be a great opportunity to learn what we can.  We will have some radar observations if all goes well and there will be plenty of telescopes aimed at it. The Goldstone radar is planning on observing the asteroid check out this page for a wealth of information.

Sooner or later we will have something to really worry about but probably not from 2012 TC4; in fact assuming nothing happens to change the predicted orbits this is as close it will get until 2079 (NEODyS2).
