The impact event happened 4 billion years ago and can be further investigated by an upcoming mission.
A gargantuan asteroid impact on Ganymede, the solar system’s largest moon, significantly altered the body’s axis, according to a newGanymede is a Jovian moon that is larger than Mercury. It’s a compelling venue for scientific research because the moon is suspected to harbor an ocean of liquid water under its icy surface.
“The giant impact must have had a significant impact on the early evolution of Ganymede, but the thermal and structural effects of the impact on the interior of Ganymede have not yet been investigated at all. I believe that further research applying the internal evolution of ice moons could be carried out next,” Hirata said.
