Tethys
Tethys is currently about 1,263,144,900 kilometres from Earth, or 8.444 astronomical units, which puts a one-way radio signal 70.2 minutes out. It is 9.434 astronomical units from the Sun.
A bright, icy moon scarred by the giant Odysseus crater and a vast canyon system stretching most of the way around it.
Its density suggests it is made almost entirely of water ice.
