What are the diameters and sizes of the nine planets in the solar system? Simple.

Now it is the volume of the eight planets: (based on the earth, it is 1) Sun: Jupiter: Saturn: Uranus: Neptune: Earth: Venus: Mars: Mercury =1300,000:1330: 745: 65: 60:/kl.

Mass: (taking the earth as 1) Sun: Jupiter: Saturn: Uranus: Neptune: Earth: Venus: Mars: Mercury = 330000: 318: 95:14.53:17./kl. In the radius of gyration, there is a set of "Titius series" that can reflect this relationship: 0, 0.3, 0.6, 1.2, 2.3, 4.8, 9.6, 19.2 ... Add 0.4 to each item to get another set of series: 0.4, 0.7, 65433. 10, 19.6 ... If the distance from the earth to the sun is taken as a unit of measurement (astronomical unit), the distances from the eight planets to the sun (except 2.8) all conform to this series relationship. This is also one of the reasons that prompted people to discover the asteroid belt between Mars and Jupiter.
