The rings of Uranus in new images from the Webb telescope

Uranus is the seventh planet in the solar system. It is a gas giant, although scientists sometimes refer to both Uranus and Neptune as ice giants. This is because the atmospheres of these planets, which consist mainly of hydrogen and helium, contain more frozen volatiles than the larger gas giants.

Uranus has a ring system, many moons and is the coldest planet in the solar system. The lowest temperature there is minus 224 degrees Celsius. In addition to the coldest atmosphere, Uranus also has its axis of rotation, which is strongly tilted and lies roughly in the plane of the planet’s orbit. Therefore, its poles are located where the equator of most planets in the solar system is. This causes confusion with the seasons compared to other planets, as the planet’s poles experience many years of continuous sunlight followed by the same number of years of complete darkness (Uranus takes 84 years to revolve around the sun).

What could cause Uranus to tilt sideways? Scientists believe Uranus may have collided with an object about twice the size of Earth in the ancient past (more on this in the text: Uranus was hit by an object twice the size of Earth. catastrophe billions of years ago).
