 In addition to Jupiter and Saturn there are two ice cream giants, Uranus and Neptune, Uranus is one of the most enigmatic planets, what little we know is thanks to Voyager 2.

 Uranus (in honor of the Greek god) is the seventh planet in the solar system, the third in size and the fourth most massive, measuring more than 51,000 km in diameter, is more than 3,000 million km from the Sun, takes 84 years to complete an orbit around the sun, it is the 2nd with the most rings, but these rings are made of very dark materials which complicates its observation.

 Uranus has 27 satellites, but only 5 are important: TITANIA, OBERON, UMBRIEL, ARIEL AND MIRANDA.

 From Uranus to Neptune there are 11 AU, as the composition Uranus is similar to Neptune, both cataloged as the ice giants.

 Temperatures reach -226°C, the atmosphere is mainly composed of hydrogen and helium, its pale blue-green color is a result of the presence of methane.  It turns in the opposite direction to the way most planets rotate.  The biggest peculiarity is that its axis of rotation is completely rotated, perpendicularly to the axis of rotation of the sun, it is unique.  Scientists believe that a planetary collision took place a long time ago that tipped the planet over.

 Here winds reach speeds of up to 900 km / h, below the atmosphere temperatures rise very slowly, it is the coldest planet in the solar system, unlike Jupiter and Saturn in its interior the temperatures barely rise, it is believed that the planet it has a much cooler core.  At 10% below its gaseous environment it becomes a liquid state little by little as it descends, the inner atmosphere is bound and wrapped around the mantle of chemical compounds including water, ammonia and methane, this ocean of water and ammonia has high electrical conductivity .

 Uranus has under its surface a frozen mantle over a rocky core, which gives it a series of special characteristics, properties that allow them to play with chemical laws to form substances that shouldn't exist.

 On the planet's mantle pressures reach up to 4 million terrestrial atmospheres, with these pressures and their chemical composition, under the mantle there could be chemical substances that could not exist anywhere else in the solar system.

 Uranus loses mass little by little because its magnetic field is inverted towards the equator, this makes it more vulnerable to the solar wind which is the cause of its mass loss, Uranus is losing its atmosphere through its magnetic field, detecting plasma bubbles in your field.

 Voyager 2 has left Uranus behind and is now an interstellar probe, other telescopes such as the mighty James Webb will certainly be able to reveal to us new data about this distant world, despite our advances in astronomy we don't even know a billion dollars of our universe What do you expect us to discover that unsuspected new wonders we will have discovered in a generation?  and in another one?...
