Some of them, such as Saturn, Jupiter, Uranus and Neptune, additionally possess
planetary rings — a collection of still smaller bodies of different sizes that
also orbit a planet.
Taken together, the two results make a compelling case for young
rings, says Larry Esposito, a
planetary scientist
also at CU Boulder who has long believed the
rings to be old.
By drilling into a circular ridge inside the 180 - kilometer - wide crater rim, researchers
also hope to nail down the processes that form «peak
rings»: hallmarks of the largest impact craters, which
planetary scientists have seen elsewhere in the solar system but which erosion has erased from other big craters on Earth.
