Planet Uranus: characteristics and temperature


The planet Uranus it is not one of the planets that immediately come to mind to list, the classics that come to mind are others such as for example Venus, Mars and possibly Saturn because of its eye-catching rings. Yet even Uranus has several interesting features to explore and learn about, no inhabitant currently identified but many "gases". Let's start to discover this big and distant planet.

Planet Uranus: characteristics

One of the first features with which the planet Uranus it is framed is its gaseous being, it is not the only celestial body to be, however, and if you remember well we have also spoken of Jupiter and Saturn in a similar way. Here, it can be considered in a certain sense their younger brother given the numerous similarities between these three planets. A similar argument can also be made comparing Uranus with Neptune.

First of all, however, we must specify that the planet Uranus has not been known for too long, at least compared to his other colleagues, it was in fact discovered in 1781 by Herschel. It was and is necessary to have good tools to observe it, it is in fact too distant to be seen with the naked eye. Today, however, we are able to describe it well and we can say that it has a “smooth” appearance, devoid of structures, and is of a green-blue color.

We also studied the characteristics from a physical and chemical point of view, and astronomical, ascertaining that its gravity was not sufficient to retain the light gases of its atmosphere, hydrogen and helium. That's why only the heaviest gases are left on the planet Uranus: water vapor, ammonia and methane. The latter present in abundance, is responsible for the bluish color that the planet presents.

When compared to the other gas planets, Uranus looks small, and it is small compared to Jupiter or Saturn, but it must be said that it has a mass 14 times greater than that of the Earth, to make the idea it is large enough to contain over 60 planets like the Earth. Other than small!

Planet Uranus: time

How long does one day last Uranus? And a year? We can find out by going to understand how it moves. It rotates around its axis in 17 hours and 14 minutes so this is the length of the day on the planet, but there is one thing that distinguishes it from all other planets and that concerns its rotation on itself because it does so with respect to an axis that is tilted 98 degrees on the plane of its orbit.

What does it mean? That Uranus is a practically "lying" planet that alternately turns the two poles to us, which is also why i poles of Uranus they receive much more light and heat than the equator does. On Earth and other planets this does not happen. With regard to light, however, a clarification must be made, for completeness. The planet we are talking about is far farther from the Sun than the Earth, 19 times more, it goes without saying that at that distance, it receives only 0.3% of the sunlight that our planet receives.

We come to the motion of revolution and the length of the year on Uranus which lasts 84 times that of Earth. All things considered, it has only completed two and a half orbits, almost three, since it was discovered.

Planet Uranus: temperature

Strong winds blow on Uranus, with speeds up to 600 Km per hour and there is a very intense magnetic field, a feature that we have also found in other gas planets. Ours is composed of hydrogen, methane and helium, is blue-green, has a diameter of 46,650 km (about 4 times that of the earth) and is 2,870 million kilometers from the sun.

A lot, I would say, and this makes its temperature very cold, we hover around -200 ° C. If we go to investigate how it is composed inside, we find a large rocky core surrounded by ice, on the outside, however, there are rings arranged on 11 bands, they are formed by rock and dust, dark in color, and it is not easy observe them unless you have powerful telescopes in your hands.

When Uranus was visited in 1986 by the Voyager 2 probe, which has collected a lot of information about the planet and its rings, it was also possible to notice the presence of its 15 satellites, 10 more than were thought to have been before this mission. Will there be others? It may be, at the moment the biggest turn out to be Titania, Oberon, Umbriel, Ariel and Miranda. All satellites bear the names of characters from the works of Shakespeare and Pope, the two great English poets of the 16th and 17th centuries.

Uranus in astrology

Recently discovered, compared to the others, gaseous and distant, and "lying", this planet can only represent everything that is out of the ordinary, the rebellious side that hides in each of us. This planet dominates in subjects with a drastic character, who do not know mince words. The person who has his Sun in aspect to Uranus will have a certain degree of unpredictability in his character and an intolerance to the rules, an open mind and projected towards tomorrow.

In practical life, Uranus is associated with everything to do with new technologies and with the sciences that study social structures. Electricity is under its dominion as well as disciplines such as architecture, engineering, politics, occasionally even Art.
