Animation of Neptune’s moon Hippocamp

This artist's impression shows how the smallest known moon of Neptune, now named Hippocamp, might look close up.

In the animation the camera rotates once around the tiny moon, showing first the distant Sun and at the end the planet Neptune, which the moon is orbiting.

While the NASA/ESA Hubble Space Telescope allowed researchers to discover the moon and to measure the its size, the images from Hubble do not allow us to see surface structures.
