Saturn Regains Crown as Solar System’s Moon King

Astonishing Discovery of 62 New Moons Elevates Saturn Above Jupiter, Cementing its Status as the Moon-Rich Planet in our Solar System.

In a cosmic twist of events, Saturn has reclaimed its throne as the reigning ‘moon king’ of our solar system. This comes after the recent discovery of 62 new moons orbiting the ringed planet, elevating its total moon count to a staggering 145.


Astronomers have recently identified 62 new moons orbiting Saturn, bringing its total moon count to 145, the highest in the solar system. The newly discovered moons are classified as “irregular moons,” with most of them belonging to the densely populated Norse group. The discovery, led by Edward Ashton, was made using the “shift and stack” technique, a first for Saturn. This discovery not only reinstates Saturn as the ‘moon king’ but also offers valuable insights into the history of cosmic collisions in the gas giant system.

A Cosmic Game of Thrones

Saturn, the second-largest planet in our solar system, was once known for having the most moons. However, in February 2023, Jupiter momentarily stole this title, boasting a total of 92 moons. This brief period of Jupiter’s reign has now ended with the discovery of 62 new moons orbiting Saturn.

An Unprecedented Discovery

The groundbreaking discovery was made by a team led by Edward Ashton, a postdoctoral fellow at the Academia Sinica Institute of Astronomy and Astrophysics. They employed a technique called “shift and stack,” which uses a series of images moving at the same speed as a moon to enhance the signal from that moon. This novel method allowed the detection of moons around Saturn as small as 1.6 miles in diameter – roughly two-thirds the length of Hollywood’s Walk of Fame.

Saturn’s Irregular Moons: Unveiling a Violent History

The newly discovered satellites are classified as ‘irregular moons,’ believed to be remnants of larger moons that collided and fragmented. These irregular moons orbit Saturn on large, flattened, or elliptical paths, providing crucial clues about the planet’s violent past. By studying these moons, astronomers hope to better understand the history and frequency of such cosmic collisions.


Research Scopes:

This groundbreaking discovery opens up new avenues for research in astronomy. Future studies could focus on further refining the “shift and stack” method to discover even smaller moons. Additionally, by studying the orbits and compositions of these irregular moons, scientists may gain further insights into the history of collisions in the Saturn system, potentially revealing more about the formation and evolution of the entire solar system.
