Meteor Keywords
- A meteor or “shooting star” is the visible streak of light from a meteoroid, heated and glowing from entering the Earth’s atmosphere.
- Most meteoroids that cause meteors are about the size of a pebble or less.
- Meteors become visible between about 30 – 70 miles above the Earth.
- Meteors may occur in showers, which arise when the Earth passes through a stream of debris left by a comet.
Fireball
- A fireball is a brighter-than-usual meteor as “a meteor brighter than any of the planets”
- Fireballs reaching magnitude -14 or brighter are called bolides. (See the Space.com – video.)
- Rarely to be seen.
Keys
- Beginning & ending date: Date in which the Meteor Showers will begin and end.
- Peak Date: Date in which the Meteor Shower should appear most active as best visible.
- Rating: Rough estimate of possibility of how good the Meteor Shower might be.
- Zenith Hourly Rate: Approximate number of meteors (shooting star) that will be visible per hour.
- Radiant Position: Mark the location in the sky.
- Degrees: Directions correspond to the following degrees by a compass.
- Comet: Earth passes through a stream of debris left by which comet? (parent object.)
- Note: Something to say.
