The gas giant is made up mostly of hydrogen and helium, with 82 moons that orbit it.
Nasa research in 2018 showed that the planet is losing its rings, which are being drawn by gravity into Saturn as a dusty rain of ice particles.
“In this new study, the rate of water flow into the planet is estimated to be one Olympic-sized swimming pool every half an hour, meaning Saturn's rings will be gone in under 300 million years,” Nasa said on its website when the study was first released.
“This is short relative to the 4.5 billion-year age of the solar system. The findings suggest that giant planetary ring systems are not built to last for ever.”
