Uranus is personal. The poles of most planets in the solar system are more or less the same direction. Viewed from above, most of them rotate counterclockwise. But Uranus? its The rotation axis is oriented at 98 degrees relative to its orbitAnd it rotates clockwise.

This weird main assumption is Big things smash into Uranus Long ago, I hit my butt on the teapot. Although this situation is not impossible, there are still some considerable holes in this model.

Don't be afraid, though. Astronomers at the University of Maryland have come up with a new solution that can cleverly solve these problems. No, Uranus is not drunk Comet wine It fell but it may have been tilted sideways by a huge ring system.

No doubt, "Wait a minute," Uranus doesn't have a huge ring system. That's right. Right now, it doesn't-compared to Saturn's brilliant spread, its ring is faint and sparse.

But the latest evidence from Cassini suggests that the ring could be Temporary and transient -As a result, Uranus is likely to have a broader system in the past 4.5 billion years.

The problem with sm models is mainly related to what is around the planet. For example Neptune. If you watch the awesome video below, you will find that the rotation cycles of Neptune and Uranus are similar.

The similarity of these spin cycles means- Just like Jupiter and Saturn -Two planets are born together. If you have one or more effects large enough to tilt Uranus to the side, the of a spin-like cycle is greatly reduced.

Uranus' moons are also a problem. The sudden tilt caused by the impact may damage and destabilize its satellite system, but the ice planet's satellites are similar in size and spacing to ice satellites. Galileo satellite.

Those satellites are also cold. An impact sufficient to overturn the planet should have generated enough heat to evaporate any ice on these satellites, making them mostly rock, but all the major satellites of the planet have at least equal parts of rock and ice.

According to astronomers Zeeve Rogoszinski and Douglas Hamilton of the University of Maryland, these problems can be solved if Uranus' ring system is large enough to make it swing on its axis like a spinning gyro. Precession -And if the precession is consistent with the planet Orbit precessionThe ellipse moves slowly around the sun.

You can see the animation of these two concepts below.

This alignment of motion is called resonance, and it occurs several times in the solar system-usually in Orbit of two or more objects. For example, Pluto and Neptune have a 2: 3 orbital resonance, which means that for every two of Pluto's orbits around the sun, Neptune orbits 3 times.

The resonance between a planet's precession and its orbital precession is called a secular spin orbit resonance, which can produce a large axial tilt. Think this resonance Could have been For example, a larger axial tilt was introduced on Saturn than on Jupiter.

Regarding the tilt of Uranus, long-term spin-orbit resonance has been explored, but it is related to the resonance caused by the hypothetical ninth planet. finally Discarded Extremely unlikely.

However, Rogoszinski and Hamilton suggested that larger discs might be more appropriate. They simulated Uranus and Neptune with large discs to see how they interacted with the planet. They found that a large mass of matter has accumulated on the planet-we know it is Part of the forming process Largest planet-most suitable.

But even if it produced the best results of all models, it still couldn't make Uranus completely. Over a million years, it only produced a tilt of 70 degrees. This means that the Great Prosperity Theory still exists.

However, any hitting rocks needed to push Uranus toward the rest will be much smaller and therefore more likely.

"Although we rarely produce greater than 70 degrees, and we cannot make them more than 90 degrees, subsequent collisions with objects about half the mass of the Earth may tilt Uranus from 70 degrees to 98 degrees." The researchers wrote in the paper.

"Reducing the number and number of giant impactors from two or more to one will increase the of Uranus spin states by about an order of magnitude."

These are only temporary assumptions, and still pending, but one thing seems certain: Uranus, comet wine is still not there, it must be a crazy period.
