What's nice when the sun rises and sets at the same time maybe is that we know when it's time to enjoy the view of the sun in the morning and evening. However, something changes when the sun rises and sets at the same time.
Some of the things that are different is that the Earth has to move around the sun in a perfect circle, folks. Then the Earth's axis is perpendicular to the plane of its orbit, i.e. straight up and down. If the two things above happen, then the sun will also be seen passing the same path in the sky throughout the year.
However, our Earth does not have an orbit that is a perfect circle. As we know, Earth's orbit is slightly elliptical. This makes the sun travel through the sky at different speeds depending on the position of the Earth in its orbit around the sun. Earth's axis is also not perpendicular to its orbit. Earth's axis is slightly tilted at about 23.4 degrees.
This is why some regions of the Earth have four seasons. When the northern hemisphere faces the sun, the inhabitants of that part of the Earth experience summer. This makes the sun appear high in the sky. On the other hand, in winter, the northern hemisphere is not facing the sun, so the sun is not as high as in summer. The tilt of the Earth's axis also makes the summer solstice phenomenon which usually occurs on June 21 in the northern hemisphere.
This summer solstice phenomenon makes the days longer. On the other hand, in June people in the southern hemisphere experience a winter solstice where the sun appears very briefly and the nights are longer. Starting from the time of sunrise and sunset, different seasons and solar phenomena, influenced by the rotational movement of the Earth that is not straight and the tilt of its axis.
