NASA's Cassini spacecraft captures Saturn's moon Tethys shining over the planet's north pole.

Even though its been more than a decade since NASA’s Cassini spacecraft arrived at Saturn, it is still capturing spectacular images of the planet and its numerous moons. In the latest image taken from Cassini, Saturn’s moon Tethys seems to be hovering right over the planet’s north pole. But it is just an illusion of perspective which is making the moon appear to hang above a different place than it actually is. Like all of Saturn’s major moons and its ring system, Tethys also orbits almost exactly in the planet’s equatorial plane. 

The image focuses the sunlit side of the planet as we see it from the spacecraft. The image was taken with wide-angle camera on board Cassini using a spectral filter and at a distance of approximately 2.1 million miles. 

Tethys is one of the 62 known moons orbiting around Saturn. The moon is mainly made of water ice and harbors several craters. Due to some interesting features caused by impacts and object’s geology, this moon has become a major source of interest for scientists and astronomers. 

Originally discovered in 1684, Tethys is 660 miles in diameter and is the 16th largest moon in our solar system. Like many other natural satellites of Saturn, the name of Tethys also came from Greek Mythology and it was named after Titan Tethys, a mythological sibling of Cronus.
