1) The equinoxes look at the return year, the aphelion and the sidereal year, which are different 2) The beginning of January is at perihelion, and the beginning of July is at aphelion. The distance can always be seen 3) "oblique revolution" and "horizontal revolution" are not solved? It is used to accurately standardize the point 4) The teacher's comprehension process in class will be understood if you understand it, and if you don't understand it, you will remember the conclusion.
Why does the yellow-red angle change?
There is no such thing as perfect movement in nature.
The Earth's axis points to the North Star, but is the plane on which the Earth's axis is located perpendicular to the ecliptic plane?
Can you consider the phrase "the plane where the earth's axis is located".
It's tempting! Your question is really unbearable, you don't listen to what you should listen to, you don't remember what you should remember, and then your conscience finds out? Huh
Don't study your pig too many problems, the teacher said that you should memorize it, the questions will not be done, I will tell you, your pig problems are meaningless, and many conclusive things are not very difficult to remember. Actually, I can tell the reason and remember it with understanding, but I have done experiments on more than 400 people, and not everyone can understand it.

1.The winter solstice is on December 22, and the summer solstice is on June 22.
The perihelion is in early January and the aphelion is in early July.
2.According to the time of day according to the distance from the sun.
-
You confuse several relationships.
The equinomy is related to the direct point of the Sun, not to the perihelion or aphelion.
Perihelion aphelion has little effect on the Earth.
You're so long, you should ask separately - -
-
2 minutes and 2 to refer to the angle of the sun that has nothing to do with the near sun.
Far away and today, in July and January, you should be able to see the distance on the chart.
-
The farthest point from the Sun is the aphelion.
The closest point to the Sun is perihelion.

Ask your teacher!! So much.

The rotation of the Earth. The diurnal variation on the earth is produced, and the earth revolves.
This has led to the alternation of the seasons. The earth has a rotation from west to east around the axis of rotation with an average angular velocity.
It rotates 15 degrees per hour. At the Earth's equator, the linear velocity of rotation is 465 meters per second. The phenomena of the heavens and bodies rising in the east and setting in the west are all reflections of the rotation of the earth.
The orbit of the Earth's revolution is elliptical, the orbit of the revolution is 149597870 km in half-length, and the eccentricity of the orbit.
, the average orbital velocity of the revolution is kilometers per second. From the Earth, the sun moves counterclockwise along the ecliptic, and there are two intersections on the celestial sphere at a distance of 180° between the ecliptic and the equator, of which the point where the sun passes through the celestial equator from the south to the north along the ecliptic is called the equinox.
-
The main phenomenon caused by the rotation of the earth is the alternation of day and night when the sun rises in the east and sets in the west, of course, wind belts, ocean currents, auroras and typhoons are also related to the rotation of the earth. The phenomena produced by the rotation of the earth are mainly the alternation of the four seasons of the year, the polar day and the polar night at the north and south poles, etc.
-
The Earth's rotation creates a day-night alternation, time zones, and rotational deflection forces, which further lead to the creation of barometric and wind belts. The rotation of the Earth produces the changes of the four seasons throughout the year, the north-south movement of the direct point of the sun, and the formation of the four seasons on the earth.
-
The rotation of the earth produces the scene of a day such as day, night, morning, dusk, etc., while the rotation produces the seasonal changes of spring, summer, autumn and winter.
-
The rotation of the earth produces the phenomenon of day and night; Different longitudes have different local times; deflection in the direction of objects moving horizontally along the surface; Effect on the shape of the Earth.
The regional revolution produces differences in the height of the sun at noon and the length of day and night, forming the four seasons and the five bands.
-
The model of the phenomenon produced by the rotation and revolution of the earth is the alternation of white nights and the alternation of seasons.
Don't simply look at things as they look!
The relatively stable relationship between the earth and the sun is the balance of the gravitational pull of the sun on the earth and the centrifugal force of the earth's revolution. >>>More
Let's first briefly understand rotation and revolution, rotation refers to the movement of the object to rotate on its own, and the three-dimensional object around the axis of rotation is called the axis of rotation or axis of rotation, if the axis of rotation passes through the objectCentroid, the object is said to be rotating, and this axis is called the axis of rotation. Orbital revolution, on the other hand, is the circular motion of an object along a certain orbit centered on another object. >>>More

Yes, frictionless motion does not require force to maintain, so the revolution of the earth has nothing to do with the sun. Assuming that the gravitational pull of the Sun could cause the Earth to accelerate from a standstill, the Earth would have to continue to accelerate, not as it does now. If it really all started at rest, there would be only the sun left in the solar system, because everything fell into it. >>>More
