Mercury is so small and close to the sun that imaging more than just a featureless disk is beyond the capability of my equipment. Venus is completely cloud covered and therefore, seeing surface features with optical equipment is never possible. Both planets exhibit phases as seen from the Earth. Full resolution photos are shown here.

Seasonal variations on Mars produce changes in its northern and southern polar ice caps. Mars also exhibits shape phases as seen from Earth. Mars has two moons, Phobos and Deimos.

Jupiter's surface is entirely gaseous, and various patterns in the atmosphere can be seen. The most prominent features are two dark bands and the giant red spot which is an enormous storm that has persisted for centuries. In 1989, one of Jupiter's distinctive bands faded away, and was visible again a few years later.

This large planet rotates 360 degrees in only 10 hours, so its giant red spot is only visible for 5 hours at a time. Jupiter has between 80 and 100 moons. The four closest and largest moons are Io, Europa, Ganymede, and Callisto.

When one of Jupiter's large moons is between the Sun and Jupiter, a shadow of the moon is cast on the surface of the planet.

Comet Shoemaker–Levy broke apart in July 1992 and large pieces collided with Jupiter in July 1994, causing several large impact scars in the atmosphere that persisted for many months. In my photo taken on 22 July 1994, you can see dark impact scar areas at the top of the planet; two scars are just to the right of center and the other scar is near the left top edge.

Saturn has at least 83 moons. As seen from Earth, the tilt angle of its rings changes. Every 13 to 15 years, Earth passes through the plane of Saturn's rings, and when seen edge on, they almost disappear.

Uranus and Neptune are so distant that imaging more than just a featureless disk is beyond the capability of my equipment. Full resolution photos are shown here.
