This December 21 will be a sidereal show.

Three events coincide between dusk this Friday and early Saturday morning.

The first is really the internship where the other two will occur. This Friday is the solstice, which produces opposing phenomena in each hemisphere.

In the northern hemisphere is the day shorter of the year and therefore the longest night of the year. There it is called the winter solstice.

In the southern hemisphere, on the other hand, it is the longest day and the shortest night of the year, and it is called Summer Solstice.

The solstice occurs due to the inclined way in which the Earth revolves around the sun. Thus, the amount of light which receives each part of the Earth is different throughout the year. The solstice marks the two moments, June and December, when the Earth reaches its greatest inclination toward the sun.

After the winter solstice in the northern hemisphere, the days gradually begin to be longer, which is why many cultures celebrated as a stage of rebirth.

This rain is called urisids because it seems to come from the constellation of Little Bear. Ursidus is a synonym for bear.
