You must have heard the name of the planet Arun, known in English as Uranus, which is the seventh planet from the Sun among the eight planets. It is the second farthest planet from the Sun after Neptune. Sir William Herschel first observed Uranus on 13 March 1781, leading to its discovery as a planet. You will be surprised to know that Uranus is the first planet in the solar system, which was discovered by telescope. This beautiful planet has many more amazing facts which will be discussed in this article.
Uranus completes one round on its axis in about 17 hours and 14 minutes that means a day on Uranus is 17.14 Earth hours while a day on Earth is 23.934 hours, and one year on Uranus equals 84 years of Earth, which means it orbits the Sun once every 84 years. You will be very surprised to know that Uranus has 42 years' night and 42 years' day. The reason for this is that on Uranus one of the two poles faces the Sun continuously and the other faces away. Each pole gets around 42 years of continuous sunlight, followed by 42 years of darkness. The axis of Uranus is tilted at an angle of 98 degrees with respect to its orbit, which is approximately parallel with the plane of the Solar System, and this gives it seasonal changes completely unlike those of the other planets. Earth’s axis is tilted 23.5 degrees from the plane of its orbit around the sun.

With a radius of 25,362 km, Uranus is the third-largest planet in the Solar System, only Jupiter and Saturn are bigger than Uranus, but with a mass of 86.8 x 1024 kg, it is the fourth most massive which is 14.5 times the mass of Earth. It the second least dense planet, after Saturn. One of the most abundant components of Uranus' atmosphere is methane. The cold methane gas gives Uranus its blue-green color. NASA's Voyager 2 remains the only spacecraft to visit the planet, which made its closest approach to Uranus on January 24, 1986. The NASA's spacecraft studied its cold atmosphere, examined its ring system, and discovered its 10 moons. It also returned spectacular photos of Uranus' five large moons, revealing that their surfaces are covered with canyons and impact craters.

Like Jupiter, Saturn and Neptune, Uranus is also composed of gases and hence this planet is also called a gas giant because it has mostly gas instead of other materials and has a very huge size. Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. Uranus is similar in composition to Neptune and these two planets are also called Ice Giants due to some differences from the other Gas Giants i.e. Jupiter and Saturn. The atmosphere of planet Uranus is completely similar to that of Jupiter and Saturn in its primary composition of helium and hydrogen but it is composed mainly of heavier volatile substances, known as "ices" that include water, ammonia, and methane, along with traces of other hydrocarbons.
Like the other giant planets, Uranus has a ring system, a magnetosphere, and numerous moons. Rings of Uranus are so light that they do not appear a lot, so most people have no idea about its rings. Its rings are composed of extremely dark particles, which vary in size from micrometers to a fraction of a meter. Like the rest of the large planets, Uranus also has several moons. Uranus has a total of 27 natural satellites i.e. the Moons, although most of them are very small and irregular. Five of the moons are large and the rest are much smaller. The moons of Uranus are divided into three groups: thirteen inner moons, five major moons, and nine irregular moons. The inner moons are small dark bodies that share common properties and origins with Uranus's rings. The five large moons are called Titania, Miranda, Oberon, Umbriel, and Ariel. Titania is the largest moon of Uranus. And irregular moons of Uranus have elliptical and strongly inclined orbits at large distances from the planet.

Uranus is about 2.964 billion kilometers away from the Sun and it receives very little in terms of light and warmth from the Sun and that is why its atmosphere is the coldest in the solar system. Uranus has an average temperature of -197 degrees Celsius and according to scientists, Uranus has the lowest recorded temperature of -224 degrees Celsius.
