Size comparison of Earth and Uranus. Uranus's mass is roughly 14.5 times that of Earth, making it the least massive of the giant planets. Its diameter is slightly larger than Neptune's at roughly four times that of Earth. A resulting density of 1.27 g/cm 3 makes Uranus the second least dense planet, after Saturn.
With an equatorial diameter of 31,763 miles (51,118 kilometers), Uranus is four times wider than Earth. If Earth was the size of a nickel, Uranus would be about as big as a softball.

The mean radius of Uranus is 15,792 miles (25,362 kilometers), giving a diameter four times that of Earth. "If Earth were a large apple, Uranus would be the size of a basketball," NASA's Science websitesays. But like many other bodies in the solar system, the rapid spin of Uranus causes a slight bulge around the center. At the poles, Uranus has a r...
Although Uranus, discovered in 1781, is only four times the physical size of Earth, it is significantly more massive, weighing in at 86 septillion kilograms (just under one trillion trillion trillion). That makes it more than 14.5 times as massive as our rocky home. The planet has a volume of 6.83x1013cubic kilometers. The density of Uranus is 1.27...
Although not as famous as Saturn, Uranus does display a set of rings around its middle. The rings around Uranus are made up of tiny dark particles smaller than a meter. Only two of the 13 rings are larger than six miles across. Although the second ring system to be discovered, the rings around Uranus weren't found until 1977, when astronomers attem...
Planet Uranus Overview. Uranus is the seventh planet from the Sun, and it's the third largest planet in our solar system – about four times wider than Earth. The diameter at its equator is 31,763 miles (51,120 kilometers). Uranus is a very cold and windy planet.
4 days ago · Uranus, seventh planet in distance from the Sun and the least massive of the solar system’s four giant, or Jovian, planets. Uranus has more than two dozen moons, five of which (Umbriel, Miranda, Ariel, Titania, and Oberon) are relatively large, and a system of narrow rings.
