How long does the Earth revolve How many days does the Earth s orbit last

The earth revolves 360 degrees, it takes 365 days 6 hours, 9 minutes and 10 seconds, called a sidereal year, you say 365 days 5 hours 48 minutes 46 seconds, called a return year, is the time used by the sun to do a cycle of round-trip motion on the Tropic of Capricorn, called the direct point of the sun is the return motion.

The rotation of the earth is one day That represents one more day of thinking about you True, good and beautiful love has no limit and no defects The earth revolves once is a year That represents one more year of love for you The eternal horizon And my heart will never change Love you for 10,000 years Love you can stand the test Flying beyond the limitations of time Narrowing the plane of the region.

The time it takes for the Earth to revolve around the Sun is the Earth's orbital period. Broadly speaking, the Earth's orbital cycle is a "year". Because the period of the annual apparent motion of the Sun is the same as the period of the Earth's revolution, the period of the Earth's revolution can be measured by the annual apparent motion of the Sun.

An observer on Earth observes a "year" when the Sun passes through a certain point on the ecliptic continuously. Depending on the reference point selected, the length of the Year is also different. Commonly used periodic units are sidereal years, regression years, and perigee years.

The sidereal cycle in which the Earth revolves is the sidereal year. This period unit is obtained by using the star as a reference point. During a sidereal year, the center of the Earth, as seen from the center of the Sun, starts from a point with a star as a background, orbits the Sun, and then returns to the same point in the sky; From the center of the Earth, the center of the Sun departs from a point on the ecliptic, which is fixed relative to the star, orbits for one time, and then returns to the same point on the ecliptic.

Thus, from the geocentric celestial sphere, the length of a sidereal year is the apparent center of the Sun, on the ecliptic, the time interval between two consecutive passes through the same star.

The sidereal year is obtained by using a constant and motionless star as a reference point, so it is the time when the Earth revolves 360°, which is the true cycle of the Earth's revolution. Expressed in the unit of day, its length is day, i.e., 365 days, 6 hours, 9 minutes and 10 seconds.

The vernal equinox cycle of the Earth's revolution is the return year. This period unit is obtained from the vernal equinox as a reference point. During a return year, the center of the Earth passes the vernal equinox twice in a row from the center of the Sun; From the center of the Earth, the center of the Sun passes the equinox twice in a row.

From the perspective of the geocentric celestial sphere, the length of a return year is the time interval between two consecutive passes of the vernal equinox with the center of the Sun on the ecliptic.

Earth's orbital period: one year (days). The earth revolves around one revolution, which is roughly a "year".

365 days, 5 hours, 58 minutes, 56 seconds - solar year (return year), 365 days, 6 hours, 9 minutes, 10 seconds - sidereal year.

Answer: The Earth's orbital period is about 365 days, which is the time of one year.

The Earth orbits the Sun, and the year is 366 days. A normal year is 365 days.

The Earth's orbital cycle is 365 days, 6 hours, 9 minutes and 10 seconds, and every four years there will be one more day, and the extra day will be added to the last day of February, so every four years there is a leap year, three flat years.

It takes days or days for the earth to revolve around one week. There are two different algorithms for the Earth's orbital period. According to the method of return year (the center of the earth passes the vernal equinox twice in a row), the specific time of the earth's revolution is days, that is, 365 days, 5 hours and 48 minutes.

Another method is the sidereal year calculation method, which measures the specific time of the day, which is 365 days, 6 hours and 9 minutes.

Peculiarities of the Earth's revolutionThe revolution of the earth means that the earth revolves around the sun in a certain orbit. Just as the rotation of the earth has its own unique regularity, the rotation of the earth due to the action of the sun's gravitational field and rotation also has its own laws. The rotation of the earth follows the laws of the earth's orbit, the earth's orbital plane, the yellow-red angle, the period of the earth's revolution, the speed of the earth's revolution and the effect of the earth's revolution.

Earth's orbital cycle: days. The earth revolves around one revolution, which is roughly a "year".

There are two distinct cycles in the Earth's revolution, the return year and the sidereal year.

A sidereal year is the interval between the apparent Sun passing through the Earth twice in a row and connecting with a star (which is thought to be fixed on the celestial sphere). It is the true cycle of the Earth's revolution and is about 3652564 days.

The return year uses the vernal equinox as a reference point. Year 0 is the time interval between two consecutive passes of the vernal equinox by the Sun, which is about 8652422 days.

Revolution speed:

The revolution of the earth is a periodic circular motion, therefore, the speed of the earth includes two aspects: angular velocity and linear velocity. If we use the sidereal year as the Earth's orbital period, then the average angular velocity of the Earth's revolution is 360° per year, that is, after 360° of the Earth's revolution on the day, which is about 59 8 per day.

The total length of the Earth's orbit is 940,000,000 kilometers, therefore, the average speed of the Earth's revolution is 100 million kilometers per year, that is, the Earth's revolution is 100 million kilometers per second, that is, kilometers per second, about 30 kilometers per second

Linear speed 940,000,000km 365 days 940,000,000 seconds (365x24x3600) kilometers kilometers seconds (approximate 30 kilometers seconds.

The rotation of the earth is about 6 hours, 9 minutes and 10 seconds on 365 days, and the time taken by the earth to rotate is called a Hengnaqing star year.

The rotation of the earth also has its own laws, and the rotation of the earth has some laws from the orbit of the earth, the orbital plane of the earth, the angle of yellow and red, the period of the earth's revolution, the speed of the earth's revolution and the effect of the earth's revolution.

When we talk about the earth's orbital cycle, we can start with the rules of the year and the generation of leap years.

In the Gregorian calendar (Gregorian calendar) year, the year with a leap day is called a leap year, with 365 days in a normal year and 366 days in a leap year. Since the Earth's orbital cycle around the Sun is 365 days, 5 hours, 48 minutes and 46 seconds (conjunction), which is a return year, the Gregorian calendar sets a comic auspicious year as 365 days. The remaining time is about one day over four years, added to February, so that in a normal year there are 365 days per year, 28 days in February, 366 days in leap years, and 29 days in February.

Thus, there are 97 leap years in every 400 years, with leap years having an additional day at the end of February, and 366 days in leap years.

But then there are three more days every 400 years. Therefore, it is also stipulated that only the mountain that can be divisible by 400 in the century year is a leap year.

How to calculate leap years: The number of years in the Common Era is divisible by four, that is, leap years; divisible by 100 and not divisible by 400 for common years; A leap year is divisible by 100 and also divisible by 400. For example, 2000 is a leap year, but 1900 is not.

1. There are different algorithms for the rotation period of the earth.

1) According to the year of return (the center of the earth has passed the vernal equinox twice in a row), it is a day, or 365 days, 5 hours, 48 minutes and 46 seconds.

2) According to the sidereal year (the period obtained by using a distant star as a reference point, which is the true orbital period of the earth), it is a day, or 365 days, 6 hours, 9 minutes and 10 seconds. The Earth's orbital period used in general daily life is a quiet macro algorithm of the return year.

2. A natural phenomenon caused by the revolution of the earth.

1) The phenomenon of day and night alternation, towards the hemisphere of the sun, is day, and the hemisphere with the sun behind is night;

2) various motion rotation phenomena caused by geostrophic deflection forces in the northern and southern hemispheres;

3) Places on earth with different longitudes, when there are different places; The longitude is 15 degrees per mill, and the local time is one hour apart;

4) the phenomenon of time difference between the east and west of the travel book, and the phenomenon of biological work and rest;

5) Effect on the shape of the earth. The inertial centrifugal force generated by the rotation of the earth causes the earth to gradually expand from two stages to the equator, becoming a slightly flattened spheroid.
