Uranus is the third largest planet in the solar system. It orbits the Sun at a distance of about 2.8 billion kilometers (1.7 billion miles) and completes one orbit every 84 years. The length of a day on Uranus as measured by Voyager 2 is 17 hours, 14 minutes.
Our solar system includes the Sun, eight planets, five officially named dwarf planets, and hundreds of moons, and thousands of asteroids and comets. Our solar system is located in the Milky Way, a barred spiral galaxy with two major arms, and two minor arms.
25 Μαρ 2020 · 1 Introduction. Uranus and Neptune have masses of about 14.5 and 17 \ (M_ {\oplus }\) (Earth mass), respectively. Their sizes are about four times that of the Earth, and they are located at 20 and 30 AU from the Sun. Uranus and Neptune represent a unique class of planets in our Solar System, and are often referred as the “ice giants”.
The other planets with moons are Mars, Jupiter, Saturn, Uranus and Neptune. Some moons are large and spherical like Earth’s Moon, such as the four largest moons of Jupiter (the Galilean moons – Io, Europa, Ganymede and Callisto; see Figure 3).
Voyager 2 went on to explore Uranus and Neptune, and is still the only spacecraft to have visited those outer planets. The adventurers' current mission, the Voyager Interstellar Mission (VIM), will explore the outermost edge of the Sun's domain.
