Diona and Rhea appear as a single whole

Diona and Rhea appear as a single whole

Sometimes it all depends on the perspective. Here is an interesting image of satellites successfully disguised as a snowman. These are the moons of Saturn - Dion and Rhea, captured at an angle by the Cassini spacecraft. As a result, it seems that the two objects merged into a single whole.

Dion (above) was closer in distance to the apparatus at the time of the survey (1.1 million km), and Raya was 1.6 million km distant. Dion is 1123 km in diameter and Ray is 1528 km. But the shooting was done in such a way that they seem to be the same in size and distance.

In addition, the satellites revolve around Saturn at different distances. Diona is distant to the Earth-Moon distance and spends 2.7 days to rotate in a ring system. But Ray lives on and performs a revolution around the planet in 4.5 days. On the surface of Dione, one can find the large crater Evander, concentrated in the southern polar region, which allows the satellites in the photo to merge seamlessly. They also have a similar level of reflectivity. The composition of Dione is represented by 1/3 of the stone (including the core) and 2/3 of the ice with the supposed subsurface ocean.

Rhea is the second largest moon of Saturn after Titan. It resembles Dione in density, but it includes 1/4 of a stone mixed with 3/4 of ice. Therefore, sometimes the satellite is called “dirty snowball”.
