Saturn 20 new satellites

According to domestic media reports, the International Astronomical Union recently announced the discovery of 20 new satellites around Saturn, making Saturn beat Jupiter in a total of 82 to become the planet with the most satellites.

It is reported that these satellites each have a diameter of about 5 kilometers, of which 17 are rotated retrograde around Saturn. According to the researchers, these satellites are comets and asteroids that happen to pass through, interacting with gas dust to become a satellite around Saturn.

The observation team discovered 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 an event to collect names for Saturn’s new satellites, which must be named after the giants of the Nordic, Gaul or Inuit mythology.

Previously, Jupiter was the leader of the “Star of Satellites” for the first time in 20 years, with a total of 79 natural satellites.

In 2018, astronomers discovered 12 new Jupiter moons, increasing the number of known satellites of this giant giant planet to 79. Scientists photographed them while observing the more distant Kuiper belt objects.

The two new satellites were named “S/2016 J1” and “S/2017 J1”, 21 million kilometers and 24 million kilometers from Jupiter, respectively.

According to reports, scientists analyzed 20 images of the new Guardian by analyzing the images found on the Mauna Kea volcano on the Mauna Kea in Hawaii. The algorithm is said to 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 gathered to become the eight known planets. But Shepard believes that after Saturn was formed 4 billion years ago, Saturn’s gravity attracted the passing asteroids and comets, and they have been around Saturn since then.

Shepard said there may be more satellites around Saturn waiting to be discovered, but astronomers need larger telescopes to observe satellites less than 5 kilometers in diameter. The research team also launched a satellite naming competition, named after the role of Nordic, Celtic, Inuit mythology.
