Uranus/Ariel – Earth/Moon Size Comparison

Uranus/Ariel – Earth/Moon Size Comparison
This illustrates the relative sizes of Uranus, Earth and Earth's Moon. The images are shown at the proper relative size, but not the correct relative distance from each other. Uranus is approximately 31,000 miles (50,000 kilometers) in diameter, or about four times the size of Earth. The Earth is approximately 7,900 miles (12,800 kilometers) in diameter, or about four times the diameter of the Moon, 2,100 miles (3,500 kilometers).
