Saturn has a total of 62 moons, Rhea is the second largest moon of the Saturn and it is the ninth largest moon in the Solar System.
It is one of the heavily cratered and oldest satellites of the Solar System.
Giovanni Cassini discovered the moon on December 23, 1672.
To complete one spin on its own axis and to rotate around Saturn it takes 4.518 of Earth days.
The brightness of the moon varies based on the position relative to Saturn.
February 9, 2015 the two views of the icy moon are taken when Cassini was 57,000 and 78,000 away from Rhea.
The images captured using the green, clear, IR and UV filters were combined to create these views.
They offered the expanded range of colors visible to human eyes.
Both the views of the moon are orthographic projections facing towards the terrain.
Orthographic view is similar to the view seen by distant observer through a telescope.
Cassini is in Saturn’s equatorial plane form March 2015.
The spacecrafts orbit will remain near the equatorial plane of Saturn for the remainder of 2015.
During this year it will have four close observations of Titan , two of Dione and thee of Enceladus
