For closure…

Comets appear stationary in the sky. Movement can be seen on a day to day basis, or by a long viewing time.

Meteors flash through the sky in a second, not usually more than 20% of the sky is passed by one. Most meteors entering the atmos. are about the size of a Golf ball.

Fireballs are massive (1) meteors which last up to 20 seconds and are spectacular and colourful and sparkling. And scary, very scary when they are overhead as happened to me in 2008.

(1) Up to the size of a house as they enter but burn down to a fist size by the time they impact, or burn to nowt.

If you find a meteorite (Salt flats are a fave place) then keep it, as they are valuable to collectors (They pay Big bucks) and there could even be a diamond inside it.
