Thrymr (moon) facts for kids
Thrymr, also known as Saturn XXX, is one of the many moons orbiting the planet Saturn. It was discovered in the year 2000 by a team of scientists led by Brett J. Gladman. When it was first found, it was given the temporary name S/2000 S 7.
About Thrymr
Thrymr is a small moon. It is about 5.6 kilometers (about 3.5 miles) wide. This is roughly the size of a small town or a large mountain.
Thrymr's Orbit
Thrymr travels around Saturn at a great distance. On average, it is about 20,810,000 kilometers (about 12.9 million miles) away from Saturn. It takes Thrymr a long time to complete one trip around Saturn. It takes about 1120 days, which is a little over three years.
Thrymr's path around Saturn is not a perfect circle. It has an eccentricity of 0.453, which means its orbit is quite stretched out, like an oval. Its orbit is also tilted. It is tilted by 175 degrees compared to the ecliptic, which is the plane where Earth and most other planets orbit the Sun. It is tilted 151 degrees to Saturn's equator.
How Thrymr Formed
Scientists think Thrymr might have formed from pieces of another moon. It is possible that Phoebe, another moon of Saturn, was hit by something long ago. This collision could have sent pieces of rock flying off. Thrymr might be one of those pieces.
Thrymr's Name
The name Thrymr comes from Norse mythology. In these old stories, Thrymr is a Jotun, which means a frost giant. The name was first written as "Thrym" by the International Astronomical Union (IAU). However, the IAU later decided to add the "-r" ending to the name. This made it "Thrymr," matching the traditional Norse spelling.
