To me they look remarkably similiar even the gas giants and small rocky worlds appear more similiar than different.
You beat me to it.
The gas giants all seem somewhat similar to each other. There are a few differences like Saturn's rings but those might only be temporary, and some of
the other gas giants have rings too that are harder to see.
The rocky planets are certainly not identical to each other, but are certainly similar in that they're rocky. They were formed too close to the sun to
have the same gaseous composition that the gas giants have, and are made of more rare (denser) materials which is probably why they're smaller.
Also the planets are not static. Perhaps at one time, Mars may have had a denser atmosphere, and it obviously had liquid flowing water like the Earth.
But its size and other characteristics didn't allow it to maintain its atmosphere, but still, it looks so much like some places on Earth that some
people on ATS don't even think the Mars probes went to Mars but just sent pictures from some desert on Earth. They are wrong, but still that's an
indication of the similarity between the appearance of Mars and Earth.
