The Draconid meteors are caused when Earth collides with bits of debris shed by periodic comet 21P/Giacobini-Zinner. The comet has a 6.5-year-long orbit that periodically carries it near Jupiter.
Enrich Your Learning:
- A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky.
- These meteors are caused by streams of cosmic debris called meteoroids entering Earth’s atmosphere at extremely high speeds on parallel trajectories.
Draconid meteor shower:
- It is a minor meteor shower producing about 10 meteors per hour.
- It is produced by the grains left behind by comet 21P Giacobini-Zinner in 1900.
- The shower runs annually from October 6-11.
- They are named after the constellation Draco, where they seemingly come from.
- Draconid meteor shower is also called
- Draconids are typically a very modest shower, offering only a handful of slow-moving meteors per hour.
- In 1933 and 1946, there were thousands of meteors per hour seen in those years.
How they appear?
- Glowing streaks may appear anywhere in the sky, but their tails all seem to point back to the same spot in the sky.
- This happens because all meteors are coming towards Earth at the same angle, and as they come closer to our planet, the effect of perspective makes them seem to get farther apart.
- It’s like standing in the middle of railroad tracks and seeing how the two tracks come together in the distance.
