Earth: The Final Frontier
Planet Earth is a dense, rocky ball about 7,920 miles (12,750 km) across. It is one of nine planets circling our local star, the Sun. Earth is the only planet we know of that can support life. From space, its surface looks blue and cool, but inside it is so hot that rock can melt.
Uranus is the fourth largest planet in the solar system, much larger than Earth, and mostly made of frozen gas. The table below is a comparison of the characteristics of Uranus and Earth.
