Uranus Planet

The planet could be discovered on 13 March 1781. Earlier it was considered to be a flickering star. Uranus is the seventh planet from the Sun in our solar system. It is the third-largest planet in the solar system by diameter and the fourth-largest planet by mass. Although Uranus can also be seen with the eye without a telescope, it is so far away and appears to have such a medium of illumination that the ancient scholars never gave it the status of a planet and considered it a distant flickering star. On 13 March 1781, William Herschel announced its discovery. Uranus was the first planet to be found by telescope. The four planets in our solar system are called Gas Giant, because they contain mostly gas instead of rock and stones and they are very large in size. Uranus is one of these - the remaining three are Jupiter, Saturn and Neptune. Let's get complete information about the Mass, Internal Temperature, Magnetic Field, Atmosphere, Rotation, Moons Etc. of Uranus.


The mass of Uranus is 16.5 times that of Earth, which is the lowest among the massive planets. Its radius is slightly higher than that of Neptune and four times the radius of the Earth. As a result, a density of 1.26 g / cm3 makes Uranus the least dense planet after Saturn. This value indicates that it is mainly composed of different types of ice, such as water, ammonia, and methane. The overall amount of ice in the interior of Uranus is not known properly, different figures emerge according to the model selection, it should be between 9.3 and 13.5 of the Earth's mass.  Hydrogen and helium make up only a small part of the composite (between 0.5 and 1.5 Earth-mass). The remaining non-ice volume (0.5 to 3,4 earth masses) is made up of rocky material.

Internal Temperature

Uranus's internal temperature is apparently lower than that of other massive planets, in astronomical terms, it has a low thermal current. Neptune, which is double of Uranus in shape and composition, radiates 2.61 times as much energy into space as it receives from the Sun. The total of Uranus released from part of the infrared spectrum (ie heat) The power is 1.08 ± .07 times the solar energy absorbed in its own atmosphere. In fact, the thermal current of Uranus is only 0.072 ± 0.04 w / m2, which is .0855. W / m 2 K is approximately less than the Earth's internal thermal flow. The lowest temperature recorded in Uranus's tropopause is ४ ९ Kelvin (−226 ° C), making Uranus the coldest planet in the solar system.

Uranus is the coldest planet in the seventh position from the Sun in the solar system. So cold that you can't stay here. You know that the light of the sun should reach us for life, the way it reaches our earth. But not much light can reach Uranus because it is far away from the Sun. The Sun is about 150 million kilometers from the Earth, while Uranus is about 3 billion kilometers away from the Sun. That is, Uranus is 20 times more distant from Earth than the Sun.

Uranus- A Gas Giant

Four planets in our solar system have been called Gas Giant. That is, there is so much gas that life is not possible. Apart from Jupiter and Saturn, Uranus is called the gas giant. Gas is enough on Uranus, but this water ice is also enough. Apart from this, there is the ice of ammonia and methane gas. The stones are quite low here.

Due to this gas atmosphere, the temperature here is down to minus 224 degrees centigrade. That is, the temperature remains here up to -224 degrees centigrade, in which no one can imagine a life. The stone here is only 25 percent. Ice is 60 to 70 percent and is estimated to be 5 to 15 percent hydrogen and helium.

Magnetic Field

Prior to the arrival of Voyager 2, no measurements of the magnetosphere of Uranus were taken. Voyager's observations showed that the magnetic field of Uranus is distinct for two reasons, one because it does not originate from the geometric center of the planet and the other because it is tilted at 59 ° from the rotational axis. In fact, this magnetic dipole has shifted from the center of the planet to the south rotational pole as much as one-third of the planetary diameter. This unexpected geometrical result in a high asymmetric magnetosphere, where the strength of the magnetic field on the surface in the southern hemisphere is at least 0.1. Gauss can be (10 µT), similarly, it can be the highest 1.1 gausses (110 µT) in the northern hemisphere. The average field force on the surface is 0.23 gauss (23 µT). Comparison For, the Earth's magnetic field is roughly powerful at both poles and the 'magnetic equator' is roughly parallel with its geographic equator.


There are 27 known natural moons of Uranus. The moons of Uranus are:

Ariel, Belinda, Bianca, Caliban, Cordelia, Cressida, Cupid, Desdemona, Ferdinand, Francisco, Juliet, Mab, Margaret, Miranda, Oberon, Ophelia, Perdita, Portia, Prospero, Puck, Rosalind, Setebos, Stephano, Sycorax, Titania, Trinculo, Umbriel.

This Uranus satellite system is the least massive among Gas Giants. Its largest moon, (ie satellite), is named Titania. Titania, Miranda, Ariel, Umbriel, Oberon, etc. are the five main moons of Uranus.


You know that our Earth revolves around the Sun in about 365 days, which we call a year. But Uranus takes about 84 years to make one revolution of the sun. That is, our Earth revolves around the Sun 84 times, then Uranus is able to make one revolution of the Sun.
