Uranus
Uranus is so far from the Sun and us that it does not shine very brightly in the sky, although it is still detectable with the naked eye under very dark skies. It is a gaseous planet, like Jupiter and Saturn, but having a relatively higher presence of oxygen, carbon and nitrogen, it is also called an "ice giant", like Neptune. According to Greek mythology, Uranus is the father of Saturn and the grandfather of Jupiter.
| Diameter | Uranus is 50,724 km in diameter. Here we have represented it with a ball of 5 cm in diameter. |
| Duration of the day | The day on Uranus is considerably shorter than ours. It lasts 17 hours and 14 minutes. |
| Year duration | To experience a year on Uranus we would need a whole human life: 84 years. |
| Distance to the sun | It is about 19 times further from the Sun than we are, at 2,877 million km. At 2.88 kilometers from the Sun in this model represented at Garraf. |
| Satellites | 27 satellites are currently known. Titania and Oberon reach 3,000 km in diameter. |
| Composition | It is a huge sphere of gas, mostly hydrogen and helium but with a significant proportion of water ice, ammonia and methane. |
| At the level of the atmosphere equivalent to the pressure of a terrestrial atmosphere the temperature is 197 °C below zero. In the interior they surely reach 5,000 °C. |
| Gravity | We would weigh 10% less than on Earth. To get here you wouldn't have gotten so tired. |
| Density | 1.3 g / cm³. Like the density of wool. |
| Did you know... | … That the axis of rotation of Uranus has an inclination of 98 °, which means that it rotates sideways?
... That despite being the coldest planet, inside the temperature reaches 5000 °C?
… That according to some models, at the core of Uranus there is an ocean of liquid carbon on which a shower of diamonds falls? |
