It has carved a path along the inner edge of a vast, dusty debris ring encircling Fomalhaut that is 34.6 billion kilometers across. Fomalhaut b lies 2.9 billion kilometers inside the ring’s inner edge and orbits 10.7 billion miles from its star.

This big bolide (very bright meteoroid that can be visible even during day) will enter Earth’s atmosphere at about 2h30 - 2h50 UTC 7th Oct 2008 There’s nothing to worry about, this ~2 meters big rock will burn in atmosphere before reaching Earth, it will just create very pretty light show and it can be your only chance to see such bright bolide in your entire life. His path is not know yet, return here for continuous updates.

Mon Oct 6 18:25:09 UTC 2008: official ephemeride published:

The nominal orbit given above has 2008 TC3 coming to within one earth
radius around Oct. 7.1. The absolute magnitude indicates that the
object will not survive passage through the atmosphere.

Steve Chesley (JPL) reports that atmospheric entry will occur on 2008
Oct 07 0246 UTC over northern Sudan.

It is an example of Citizen science as it enlists the help of members of the public to help in scientific research. Everyone can participate!

If you have little bit of chance, you can even discover something completely new! This was the case of Dutch schoolteacher Hanny van Arkel, she discovered “strange green object“, which is probably a new class of astronomical object.
