Summer solstice: find out why today (21) is the longest day of the year

This Wednesday, December 21, the phenomenon known as summer solstice here in the southern hemisphere.

The event takes place specifically at 6:47 pm, when the planet Earth reaches an inclination of approximately 23.5º in relation to the Sun. With this, the sun's rays directly reach the line of the tropics.

Today (21) is considered the longest day of the year, as the sun's rays will reach the countries of the southern hemisphere for longer than usual.

The astronomical phenomenon marks the beginning of the summer, which happens to spring and precedes the fall. The season remains until 6:25 pm on March 20th.

Know what the solstices are

You solstices are phenomena that occur due to the movement of translation of planet Earth.

This movement directly affects our daily life, resulting in addition to the solstices also from the equinoxes.

The solstice happens when sunlight falls longer on one hemisphere than the other. This is due to the Earth's tilt on its own axis.

Thus, on the summer solstice, the day becomes longer than the night, and on the winter solstice, the night becomes longer than the day. These events mark the beginning of the respective seasons.
