(Magnitude -)4.5 (for Venus)

Magnitude is a very important detail about meteors. From American Meteor Society:  “In meteor astronomy the magnitude of a meteor is compared to that of other stars in the sky. The magnitude scale is set up so that the brighter magnitudes are actually represented by smaller numbers.”  The sun has a magnitude of -26.7 while planet Venus has a magnitude -4.5.  “A fireball is another term for a very bright meteor, generally brighter than magnitude -4, which is about the same magnitude of the planet Venus in the morning or evening sky. A bolide is a special type of fireball which explodes in a bright terminal flash at its end, often with visible fragmentation.”

For a Powers of 10 project, measure the magnitudes during a meteor shower!
