Uranus is the seventh planet in our solar system, and is twice as far from the Sun as Saturn. Uran is about 28.725 million kilometers away from the Sun. Following the time during which Uran orbits the Sun, it is approximately a little longer than the average human life. The time it takes Uran to orbit the Sun is approximately 84.1 Earth years. Uran is unique among all the planets of the solar system in that it rotates laterally. A day on this distant planet lasts approximately 17 hours, and that is quite fast for Uran. The planet is relatively large, the equatorial radius of Uranus is 25559 kilometers. Yet, because of the great distance, humans have long viewed Uranus as a star moving rapidly across the sky. William Herschel discovered Uranus in 1781 and since then the planet has been much explored.
Scientists have confirmed an average temperature on Uran of -197 ° C. Hydrogen sulfide is the main component of the atmosphere, and there is a small amount of helium and methane. Therefore, Uran is classified as a gaseous planet that smells like rotten eggs. However, Uranus probably possesses a rocky core, but this is not easy to examine. Voyager 2 is a space probe that flew past Uran in 1986. Unfortunately, the New Horizons spacecraft flew quite far from Uranus. The planet has 27 known moons that surround it. However, the number of those months is expected to increase. Uran has small rings that surround it, and it was not discovered until 1977.
