An Object 90 Miles Wide May Have Struck Jupiter’s Planet-Sized Moon Ganymede Say Scientists

The troughs that dominate the surface of the solar system’s largest Moon Ganymede may have been caused by a collision with a massive object up to 90 miles/150 kilometers wide.

That’s according to a new paper published on pre-print service arxiv.org by Japanese scientists. If the theory is true then it’s the largest impact structure identified so far in the solar system.

Ganymede is the largest of Jupiter’s estimated 79 moons and bigger than both dwarf planet Pluto and the planet Mercury. Its diameter is 3,273 miles/5,268 kilometers. It’s the only Moon Ganymede we know that has a magnetic field. It also has an atmosphere and is suspected of having an underground saltwater ocean.

Ganymede’s surface is pock-marked, grooved, and patterned. The paper argues that the furrows across its surface are part of a concentric system of tectonic troughs. “If this multi-ring structure is of impact origin, this is the largest impact structure identified so far in the solar system,” reads the paper. “The estimate of the impactor size is difficult, but a 150km-radius impactor is consistent with the observed properties of furrows.”

The scientists used images taken in 1979 by NASA’s Voyager 1 and 2 probes as well as images were taken by NASA’s Galileo spacecraft, which orbited Jupiter between 2001 and 2003.

The theory could be confirmed by future explorations of Jupiter’s icy moons, most notably by the European Space Agency’s JUICE (Jupiter Icy Moon Ganymede Explorer) mission.

JUICE is scheduled to launch between April 5-25, 2023 on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, South America. It will arrive in 2031 and spend three and a half years examining two of Jupiter’s other Moon Ganymede Europa and Callisto before going into the orbit of Ganymede in September 2032. It will become the first spacecraft to orbit a moon other than Earth’s Moon.
