It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... This meteor shower, which reaches a peak of up to 120 meteors per hour, as seen from a clear, dark site, can be observed anytime after about 10.00pm for a few nights either side of the maximum, that is from about the 12 to 16 December. The Geminid meteors, which sometimes appear as brightly coloured relatively slow-moving fireballs, are caused by small particles mostly about the size of marbles or smaller, ejected into space from the surface of the near-Earth asteroid Phaethon . ...
