Answer:
Eight planets are in rotation around our sun, the source of their energy. These fascinating planets are the main features of our Solar System, along with moons and asteroids. The planets closest to the sun are the most like Earth because they are solid, not murky swirls of gas. The top layers, or surfaces, of these planets are uneven and rocky. By any scale or measurement, Earth is the liveliest planet in our solar system because of the life it sustains. The atmospheres of the other planets are impossible for humans to breathe.
