Which planet has huge rings

Meet Jb — an exoplanet 20 times more massive than Saturn. The rings of this Super Saturn span million kilometers wide. Make no mistake, Jb is the true Lord of the Rings. Scientists ran computer simulations to model various ways in which rings of Super Saturn might go around it i.

But in the case of retrograde rotation, the rings were intact! Having retrograde rotation means that the particles of the ring system are never too close to the star for too long, and thus can stay together.

Scientists found that if the planet keeps orbiting the star, the rings will slowly disintegrate over a few thousand orbits.

Now the question is how likely is it for rings to form such that they spin in the opposite direction to the planet? That is being investigated. The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study three big quakes.

Researchers will use Webb to observe 17 actively forming planetary systems. Scientists found evidence that an area on Mars called Arabia Terra had thousands of "super eruptions" over a million-year period. Full Moon Guide: September - October Perseverance successfully collected its first pair of rock samples, and scientists already are gaining new insights into the region.

Data received late Sept. The rover will abrade a rock this week, allowing scientists and engineers to decide whether that target would withstand its powerful drill. Voyager 2 made its closest approach to Saturn on Aug. The mission revealed a planet so phenomenal scientists had to go back. Drought is a complicated problem that requires lots of data. Satellites from NASA and its partners help collect that data. The ring system consists mostly of large bodies 0.

A few rings are optically thin and are made of small dust particles which makes them difficult to observe using Earth-based telescopes. The rings of Neptune were not discovered until until the Voyager 2 space probe conducted a flyby of the planet.

Six rings have been observed in the system, which are best described as faint and tenuous. The rings are very dark, and are likely composed by organic compounds processed by radiation, similar to that found in the rings of Uranus. Back in , it was suggested that the magnetic effects around the Saturnian moon of Rhea may indicate that it has its own ring system. However, a subsequent study indicated that observations obtained the Cassini mission suggested that some other mechanism was responsible for the magnetic effects.

Years before the the New Horizons probe visited the system, astronomers speculated that Pluto might also have a ring system. However, after conducting its historic flyby of the system in July of , the New Horizons probe did not find any evidence of a ring system. While the dwarf planet had many satellites aside from its largest Charon , debris from around the planet has not coalesced into rings, as was theorized.

The minor planet of Chariklo — an asteroid that orbits the Sun between Saturn and Uranus — also has two rings that orbit it.

These are perhaps due to a collision that caused a chain of debris to form in orbit around it. For a very long time, Saturn was thought to be the only planet in our solar system with rings. The rings around Saturn were discovered by an astronomer called Galileo Galilei nearly years ago. He used a very simple telescope that he constructed himself from lenses and pointed it at the planets in the night sky. One of the first objects he looked at was Saturn.

Since then, astronomers — who study the universe and everything in it, like planets — have used bigger and better telescopes to find rings around all of the outer gas giant planets: Jupiter, Saturn, Neptune and Uranus.

These planets, unlike others in our system, consist largely of gas. The first theory states that the rings formed at the same time as the planet. Some particles of gas and dust that the planets are made of were too far away from the core of the planet and could not be squashed together by gravity.
