Tethys

By: Nick Gornie

Intro

Tethys is one of the many moons orbiting the planet of Saturn. Tethys is also one of the biggest moons orbiting Saturn. Tethys orbits Saturn every 45 hours.

Spacecrafts

The best Spacecraft to orbit the moon Tethys was the "Cassini Spacecraft". The cassini Spacecraft has taken factually the best pictures of the moon of all the Spacecrafts. (All of the pics. above were taken by the cassini spacecraft). The last year that the spacecraft visited the moon was on a september in 2005. The latest spacecraft to visit Tethys is called the "Pac-Man Spacecraft".

The moon.

Tethys is almost completely all water and ice. Tethys is also the sixth coldest moon orbiting Saturn. Tethys has a diameter of about 662 miles making it just about four times smaller than the moon Titan (Which is also a moon of Saturn). even though Titan is much bigger than Tethys, Tethys has a mass about 6 times more than Titan.

Terrain

Tethys northern portion is a old rough terrain. While the southern part is made of newer and smoother looking Plains. The smoother portion (Which is also facing away from the earth) was the part that was hit by the moon Odysseus. The impact made it so the two surfaces of Odysseus and Tethys hit together causing both of the surfaces to become smoother.
