What planets are the structure of the earth similar to?

Generally, water, gold, earth and fire are called terrestrial planets; Wood and earth are called giant planets; The sky and the ocean are called distant planets.

In terms of volume and mass, Venus is most similar to the Earth (95% in diameter and 80% in mass). But the atmosphere of Venus is much worse than that of the Earth, almost all of which are carbon dioxide (the greenhouse effect is too strong, with more than 400 degrees) and sulfuric acid clouds. It is estimated that no one can stay.

In terms of atmospheric composition and crustal material composition, Mars is closest to the Earth (composed of 95.3% carbon dioxide plus 2.7% nitrogen, 1.6% argon, 0. 15% trace oxygen and 0.03% water vapor). Although there is water and carbon dioxide, the proportional estimation of "Martians" is also false.
