|Planet Jupiter: image taken on January 3rd
2003 with Celestron 9 1/4 and digital camera Olympus C2100.
On can see the cloud structures in the atmosphere of the planet, which
ist the largest in our solar system. As we see, the shape of the planets
disc is not circular, which is due to the fast rotational speed of less
than 10 hours for one rotation.
|Planet Saturn: exposure data as above.
The rings of Saturn consist of small fragments of ice or rock, which are moving around the planet comparable a large number of small satellites.
At the outer edge of the ring one can detect the dark Cassini gap, which
is named after its discoverer. This gap is probably due to the fact that
any particle within it would have an orbital period around the planet which
is exactly half the orbital period of the satellite Mimas. So the gravitational
force of Mimas would remove any particle out of the gap.
