Cordoba prepares a new shower of the stars – Cba24n



Like every year, and in early December, it will be possible to evaluate a meteor shower called Geminids.

Its origin is a strange object called 3200 Phaethon. According to astronomers, this is a rock comet, ie. an asteroid that is very close to the Sun; It is approaching so close to the fact that the solar heat burns its dusty debris that covers its surface.

The name comes from the fact that its radiance, which is the place of the sky where meteors come, appears just above the constellation of the Gemini. All the meteors we see seem to come from that moment, their trajectories will start there.

Gemini look better in the northern hemisphere. To the south they can also be seen, but with less intensity.

The rain extends from Friday 7 to Monday, December 17, and maximum activity will be shown in the early hours of Thursday 13 to Friday 14 December.

The speed of this rain is about 120 meteors per hour most in the dark sky and the northern hemisphere. This can be seen most of the night. They are highlighted by meteors of different colors and their low speed (35 kilometers per second).

No optical instrument (either a telescope or a binocular) is needed to monitor the meteors, as our eyes better perceive meteors with peripheral vision. Also, for this reason, it is not necessary to look directly at the rays except the meteors that cross the whole sky.
