NASA has published a high-quality photo of the largest satellite of the solar system, taken from a short distance



The automatic interplanetary station Juno flew two days ago at a record short distance over the past 20 years from Ganymede, one of Jupiter’s moons. And NASA already has the first photo.

The picture was taken from a distance of only about 1000 km from the satellite. The closest thing to Ganymede at one time was the Galileo apparatus, which during one of the approaches flew only 264 km from the surface.

The photo was taken with the JunoCam instrument in visible light with a green filter. Later, NASA will receive the same image with different filters and compose a color photo. The resolution in this case is about 1 km per pixel.

In the near future, NASA will receive many other images that can be viewed on the Juno website.

Ganymede is the largest satellite of the solar system, almost 10% larger than Mercury (5268 km versus 4879 km). It is also the only satellite with its own magnetosphere, which is believed to be due to the presence of a liquid metal core. There is also a version that under a huge layer of ice, the satellite has an ocean of liquid water.
