If the sun is compared to "basketball"

The solar system is a celestial system centered on the sun, which consists of eight planets, more than 60 satellites, thousands of asteroids, countless comets and countless meteoroids. Under the gravity of the sun, the eight planets move in circles in elliptical orbits. The earth is an ordinary planet in the solar system, which is about1.500 million kilometers away from the sun.

Only the sun is the largest in the solar system, while other planets are pitifully small. The volume of the sun is about 6.5438+0.3 million times that of the earth. If the sun is compared to a "basketball" with a diameter of 25 cm, then the earth is equivalent to a "sand" with a diameter of 2.2 mm; Although Jupiter is the largest planet in the solar system, its size is only equivalent to "table tennis"; Mercury is the smallest planet in the solar system, and it is just a "dust particle" with a radius less than1mm. If the sun is placed in the center of the basketball court, almost all the planets are located outside the basketball court. The earth is about 53 meters away from the center of the basketball court. The positions of other planets are: Mercury is 20 meters, Venus is 38 meters, Mars is 8 1 meter, Jupiter is 280 meters, Saturn is 500 meters, and Uranus is.
