20 new Saturn satellites

The International Astronomical Federation recently announced the discovery of 20 new satellites around Saturn, making Saturn the planet with the largest number of satellites, beating Jupiter by 82.
It is reported that each of these satellites is about 5 kilometers in diameter, of which 17 revolve retrograde around Saturn. Researchers say these satellites are comets and asteroids that happen to pass by, interacting with gas and dust to form satellites around Saturn.
The team found these satellites through the Subaru telescope in Hawaii, and there may be more small satellites around Saturn waiting to be discovered.
The team is currently launching a campaign to name Saturn’s new satellite, requiring it to be named after giants in Nordic, Gaul or Inuit mythology.
Previously, Jupiter had topped the list of “King of Satellites” for 20 years, with a total of 79 natural satellites.
In 2018, astronomers discovered 12 new Jupiter satellites, increasing the number of known satellites for the gas giant to 79. Scientists photographed objects in the Kuiper Belt, which are more distant.
The two new satellites, named S/2016 J1 and S/2017 J1, are 21 million kilometers and 24 million kilometers away from Jupiter, respectively.
Scientists reportedly discovered 20 new Saturns by algorithmically analyzing images from the Pleiades telescope on Hawaii’s Maunaki volcano. It is said that the algorithm can distinguish between stationary stars, galaxies and satellites around Jupiter.
When the solar system was born, a large amount of gas and dust around the sun accumulated into eight known planets. But Shepard believes that after Saturn’s formation four billion years ago, its gravity attracted passing asteroids and comets, which have been orbiting around Saturn ever since.
Shepherd said that there may be more satellites around Saturn waiting to be discovered, but astronomers need larger telescopes to observe satellites smaller than 5 kilometers in diameter. The team also launched a satellite naming contest, with the naming rule that the characters in the myths of Nordic, Celtic and Inuit should be named.
