Jupiter

Jupiter and its largest moon Ganymede are shown in this image. Ganymede is slightly larger than the planet Mercury. Meanwhile, Jupiter's new 80th moon is much smaller, likely only a few dozen miles in diameter.

Kai Ly spotted the unnamed satellite using telescope images from 2003

Streaked across Ganymede's surface are bright light-colored regions of ridges and grooves that overlap darker-colored terrains along the icy shell. The textured scar-like areas suggest that the moon's surface underwent extreme geologic changes over time.
