What are the sizes of the planets?

A planet differs from a star. The star is a giant ball composed of hot gases, radiant heat and light. The planet is much smaller in size. It emits no light, but rather, is warmed by starlight.

Let’s look at all the planets in order, starting with the one that is closest to the Sun. The nearest planet to Sun — mercury. The diameter of mercury is 4878 kilometers counts, i.e. equal to the Atlantic ocean. And that means mercury is much smaller than Earth.

The next planet is Venus. It’s almost the same size as our Earth. In diameter it has about 12 100 kilometers, and the Earth’s diameter is 12 kilometers 742,5. By the way, Venus rotates around the Sun in the opposite direction, from East to West. For Venus is Earth, then Mars.
