How to compare the sizes of planets?

Arranged on paper according to a certain proportion, their sizes are as follows:

From left to right: Sun-Mercury-Venus-Earth-Mars-Asteroid Belt-Jupiter-Saturn-Uranus-Neptune.

For example, if Jupiter is regarded as a watermelon, Saturn is a grapefruit, Uranus is an apple, Neptune is a lemon, the earth is a virgin fruit, Venus is a grape, Mars is a blueberry, and the smallest mercury is just a pepper. As for the sun, it is about the size of 1000 watermelons.

memory method

Simple notation: five elements (golden wood fire, water and earth)+sea, land and air (Neptune, earth and heavenly king).

Other notation methods are: water, gold, fire, wood, earth and sea, some of which are long but easy to remember.

There is also a comment, although far-fetched, but the memory has been preserved for a long time: "A crystal ball, burning wood, has become the earth, the ends of the earth."

There is also a comment, "Water overflows Jinshan, firewood burns the earth, the sky and the sea are one, and the vast solar system". "Burning wood burns the ground", so there is an asteroid belt between Mars and Jupiter.
