Extremely bright meteor seen over northern UK
Bad Astronomy reports:
It’s too early to tell, but this may be a actual meteor – that is, a rock burning up – or it may be space debris, a piece of a satellite re-entering. Meteors tend to move quickly, zipping across the sky in a few seconds; they are moving at 20 – 50 kilometers per second and sometimes more. Orbital debris is slower, moving at less than 10 km/sec. Both have been known to break up (like the Peekskill meteor did, or the re-entry of an ATV in 2011).
