ASTEROID 2008 TC3: A small, newly-discovered asteroid named 2008 TC3 is approaching Earth and chances are good that it will hit. Measuring only a few meters across, the space rock poses no threat to people or structures on the ground, but it should create a spectacular fireball, releasing about a kiloton of energy as it disintegrates and explodes in the high atmosphere. At least one expert estimates that atmospheric entry will occur on Oct 7th at 0246 UTC over northern Sudan.

Bombay News.Net
Tuesday 7th October, 2008 (IANS)
It was a spectacular show in the sky early Tuesday morning, when a small
asteroid entered the earth's atmosphere releasing a huge amount of light
and energy before exploding.
The asteroid, 2008 TC3, entered the earth's atmosphere at 2.46 a.m.
(GMT) in Sudan (Africa). The asteroid was also visible in Europe but not in
Asia.
'Measuring only a few meters across, the space rock created a spectacular
fireball, releasing huge energy as it disintegrated and exploded in the
atmosphere,' Director of Nehru Planetarium N. Rathnashree told IANS.
The celestial activity holds significance for space scientists as for the first
time they were able to predict in advance that asteroid of such small size
will hit the earth surface Tuesday morning, Rathnashree said.
Turning down apprehensions of small asteroids causing an impact on
people and property, Rathnashree said: 'There is nothing to be panicky as
after explosion in the atmosphere only small pieces reach the ground as
meteorites'.
When a small asteroid enters the earth atmosphere, it compresses the air
in front of it. That compression heats the air, which in turn heats the
object, causing it to glow and vaporise with small pieces reaching the
earth.
Astronomers in Arizona in the US discovered the asteroid on Oct 5 as it
was inching closer to the earth.

A golf ball hit me on the cranium today. Relevant to this thread, or just a lousy putt?
