Jupiter may be the undisputed king of the planets in the solar system, but its record of 79 moons has just been smashed after the announcement of a stunning 20 new outer moons at Saturn.
Previously thought to have 62 moons, the discovery puts the ringed planet's new total at a peerless 82 moons.
Announced Monday by the International Astronomical Union's Minor Planet Center, all 20 are outer moons about three miles/five kilometers in diameter.

Which Planet has the Most Moons? What are the Most Livable ...-moons If you've been pondering about which planet has the most moons, then, look no further. Among its accolades, Jupiter has the enviable title of harboring the highest number of moons of the solar system. With an impressive 79 moons, Jupiter's moons are so many that only 53 moons have been named. The remaining 26 are currently awaiting official names.!! Studying these moons can reveal information about their

Out of all of these planets, Jupiter has the most gravity.!! The observing team included Sheppard, David Jewitt of UCLA, and Jan Kleyna of the University of Hawaii.

A Churning 'Molten Blob' of Planet May Be Easier to Find. Here's Why. | Space
The smaller a planet , the more difficult it is to spot — which is frustrating for scientists hoping to find Earth-like worlds.
That's why a team of researchers set out to determine what planetary traits would make a world a little easier to identify! Which planet has the longest day? :: The Planets Today www.the planets today.com/ which_planet _ has _the_longest_day.html Planet Mercury has the longest day of any planet in the solar system at 176 Earth days long. However, if you choose a wierd way of defining a day, then Venus has the longest day.!! Their analysis suggests that molten worlds with atmospheres full of water or carbon dioxide will be more easily observed by instruments that will be available to scientists soon.

And that's a boon for observers: If two planets have the same mass but one has a magma ocean and the other doesn't, it could be about 5% larger across, making it easier to spot. And a molten world is more likely to be leaking water and carbon dioxide from that liquid rock out into a developing atmosphere.
Those two molecules are easily released by molten rock, but they are also the sort of thing that future telescopes like NASA's James Webb Space Telescope are being designed to detect! Which Planet Has the Most Moons? | Space Questions Answered ...-moons While we only have a single moon, other planets have many more than us. Saturn has as 62 confirmed moons, but that does not compare to Jupiter , which has a total of 69 known moons. Jupiter has the most moons of any planet in the Solar System. Of the 69 moons, only 53 of them have been named. That means 16 moons have yet to be named.!! Webb won't be able to study Earth-size planets around stars like our sun, but it should be able to analyze those around smaller M dwarf stars.
Most Extreme 'Hot Jupiter' Alien Planet Completes 1 Orbit Every 18 Hours | Space
Giant alien worlds known as hot Jupiters get scorchingly close to their host stars, and now astronomers have discovered the most extreme version of such planets to date — one that zips around its star in a little more than 18 hours, a new study finds.
This exoplanet's orbit is likely decaying enough for scientists to actually measure it over the coming decade, researchers added.
In the past two decades or so, astronomers have confirmed the existence of more than 4,000 worlds outside of Earth's solar system! Planets With The Most Moons - WorldAtlas.com www.worldatlas.com /articles/ planets ...The planet with the most moons is Jupiter . Jupiter has a total of 67 moons. Experts agree that natural satellites were formed out of the same process that formed primary astronomical bodies such as planets.!! These discoveries have revealed that some of these exoplanets , such as hot Jupiters, gas giants that orbit their stars closer than Mercury does the sun, are very different from those seen in Earth's solar system.

What moons in other solar systems reveal about planets like Neptune and Jupiter

What is the difference between a planet-satellite system as we have with the Earth and Moon, versus a binary planet – two planets orbiting each other in a cosmic do-si-do?
In 2018, two astronomers from Columbia University reported the first tentative observation of an exomoon – a satellite orbiting a planet that itself orbits another star. One curious feature was that this exomoon Kepler-1625b-i was much more massive than any moon found in our solar system. It has a mass similar to Neptune and orbits a planet similar in size to Jupiter.
Astronomers expect moons of planets like Jupiter and Saturn to have masses only a few percent of Earth. But this new exomoon was almost a thousand times larger than the corresponding bodies of our solar system – moons like Ganymede and Titan which orbit Jupiter and Saturn, respectively. It is very difficult to explain the formation of such a large satellite using current models of moon formation.
Many things are taking place:
Humans will not 'migrate' to other planets, Nobel winner says
"If we are talking about exoplanets, things should be clear: we will not migrate there," Mayor told AFP near Madrid on the sidelines of a conference when asked about the possibility of humans moving to other planets.
"These planets are much, much too far away. Even in the very optimistic case of a livable planet that is not too far, say a few dozen light years, which is not a lot, it's in the neighbourhood, the time to go there is considerable," he added.

Using custom-made instruments at their observatory in southern France, Mayor and Queloz in October 1995 discovered what had previously only existed in the realm of science fiction—a planet outside Earth's solar system.
Mayor was a professor at Geneva University and Queloz was his doctorate student, when they made the discovery which started a revolution in astronomy. Since then over 4,000 exoplanets have been found in our home galaxy.
Stars that eat planets can start spinning so fast they rip apart | New Scientist
Stars sometimes bite off more than they can chew. When a star devours a planet, it can have strange effects on the star, including causing it to start falling apart. Understanding those effects could help us figure out how different kinds of planetary systems are formed.
Many planets across the universe probably end up falling into their stars, either because they stray too close, or because the stars expand as they age. We have seen some evidence of this, like clouds of leftover debris and stars full of elements they couldn't maintain on their own.
Alexander Stephan at the University of California, Los Angeles, and his colleagues calculated how planets could affect the stars that eat them. They found that a planet falling into a star can make the star brighten for anything from centuries to millennia. And that the star can spin faster as the planet deposits its energy.
