Anonymous users2024-02-05The Earth's orbit around the Sun is not circular, but elliptical, so it produces perihelion and aphelion, which are taken as the average distance of 150 million kilometers Astronomical means that the average distance of the Earth from the Sun is about 150 million kilometers, and if the eccentricity is equal to zero, it represents a circular orbit (e = 0).
Perihelion (?Approximately 147 million km.
The perihelion perihelion is about 153 million km.

Anonymous users2024-02-04The Earth's orbit around the Sun is an ellipse with the Sun at one of the focal points. It passes through perihelion (147.1 million km from the Sun) in early January and aphelion (152.1 million km from the Sun) in early July. It has been calculated that the Earth is about 8,000 kilometers closer to the Sun from morning to noon every year from aphelion to perihelion (July and January), during which the Sun at noon each day is closer to us than the Sun in the morning. Conversely, when the Earth moves from perihelion to aphelion (January-July), the Sun at noon is about 8,000 kilometers away from us every day than in the morning.
The difference between the distance between the Sun and the Earth in the morning and at noon is 8,000 kilometers, which is insignificant compared to the average distance between the Sun and the Earth (100 million kilometers), and it is difficult to observe with the naked eye.

Anonymous users2024-02-03The average distance of the Earth from the Sun is100 million kilometers
1.Since the Earth's orbit is an ellipse, this is only an average, and at the nearest place, the Earth is 147 million kilometers from the Sun, and the farthest distance from the circle is 152 million kilometers.
2.In terms of light years, the distance between the sun and the earth is light years, because the distance between the sun and the earth is about 100 million kilometers, and the distance of 1 light year is trillion kilometers, which can be obtained by dividing the two. According to the propagation speed of light, it can also be deduced that the time when sunlight reaches the earth, and it takes about 500 seconds for sunlight to travel to the earth.
3.The Earth is the third closest planet to the Sun in terms of distance from the Sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, at a distance of 100 million kilometers from the Sun.
4.The sun is a huge and hot planet of gas, and if it is too close to the sun, then the temperature of the earth will be very high, so that the moisture on the earth will not be retained, because it will soon be evaporated, and without water, it will not be suitable for human life.

Anonymous users2024-02-02The average distance of the eight planets from the Sun:
1. Mercury: 57,910,000 km (astronomical units);
2. Venus: 108,200,000 km (astronomical units) sedan car;
3. Earth: 149,600,000 km (astronomical source touching unit);
4. Mars: 227,940,000 km (astronomical units);
5. Jupiter: 778,330,000 km (astronomical units);
6. Saturn: 1,429,400,000 km (astronomical units);
7. Uranus: 2,870,990,000 km (astronomical units);
8. Neptune: 4,504,000,000 km (astronomical units).
The eight planets refer to the eight planets of the solar system, which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in descending order from near to far. Most of the eight planets also have the same rotation direction, with the exception of Venus and Uranus. Venus rotates in the opposite direction to its revolution, while Uranus rolls in orbit.

Anonymous users2024-02-01The average distance from the Earth to the Sun is: 149600000 km. Earth is one of the eight planets in the solar system, the third in order of being from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun.
The Earth rotates from west to east while revolving around the Sun.
The Sun is the central body of the solar system and occupies the overall mass of the solar system. The eight major vertebral planets, asteroids, meteors, comets, outer Neptune objects, and interstellar dust in the solar system all revolve around the Sun, and the Sun revolves around the center of the Milky Way.

Anonymous users2024-01-31This distance is defined as 1 astronomical unit.
So the average distance between the sun and the earth is 1 astronomical unit.
The sun is fast, it is the sun that catches up with the moon. Judging from the solar eclipse, it is the moon that begins to obscure the sun from the west. In this case, it's simply to shade the sun from above.
The Earth is the solar system.

When was the primordial earth born? According to the widely circulated scientific opinion, the primordial Earth was born about 50 million years after the formation of the solar system. But a new view put forward by Jacobson, a scholar at Harvard University in the United States, is that the primitive earth was formed much earlier than that. >>>More
In the early stage of growth, when the mung bean has not yet formed leaves, the mung bean in the sun grows fast because the temperature affects the catalytic efficiency of the enzyme, and the catalytic efficiency of the enzyme is higher when the temperature is suitable, and the catalytic efficiency of the enzyme affects the rate of plant metabolism, the higher the catalytic efficiency of the enzyme, the faster the metabolism speed, and the faster the plant will grow. >>>More
