When the sun rises from the east, is summer the solstice? In what direction is it set?

Unlike judging the direction on the earth, it is relatively simple to distinguish the direction of sunset and sunrise. As long as you know which season and hemisphere you are in, you can determine it according to the law. Taking the summer solstice as an example, this paper expounds how the sun rises and sets in this solar term, and analyzes the reasons for this change.

When the sun rises from the east, is summer the solstice?

No, this summer solstice is the sunrise in the northeast. There is a rule here, that is, from the vernal equinox to the autumnal equinox, that is, the sun rises from the northeast in the summer half of the northern hemisphere. Only at the vernal equinox and autumnal equinox can the whole world see the sun rising in the east and setting in the west.

In which direction did it fall?

The summer solstice is at apohelion, and the direct point of the sun is almost on the tropic of cancer. Except in extreme day and night areas, the sun rises in the northeast and sets in the northwest. At this time, the sun rises highest at noon, so the sun runs on the ground for the longest time, resulting in the longest day and the shortest night. Take China as an example, the daily length of Haikou in Hainan is a little over 13 hour, that of Hangzhou 14 hour, that of Beijing 15 hour and that of Mohe 17 hour in Heilongjiang. So near Mohe, you can see the sunset very late. It seems that after three or four hours, it will be daytime.

What is the reason?

This is due to the revolution of the earth, that is, around the sun. Its tilted axis makes the direct point of the sun on the earth constantly change. For example, in summer in the northern hemisphere, when the North Pole leans towards the sun, the time for the northern hemisphere to receive sunlight becomes longer, which means that the sun will rise before 6 o'clock, which will inevitably delay the setting time of the sun and make the sun stay in the sky for more than 12 hour. The sun moves once every 24 hours (a solar day) on the celestial sphere. If it exceeds 12 hours during the day, it means that the sun exceeds 180 in air movement. Range, and the sun is due south at 12, so the direction of the sun will rise in the northeast.
