The aspect of the gas giants that has the biggest effect on their rings and satellites is their gravity.
They are far from the sun.
They all have solid, rocky surfaces.
The sun rotates more slowly at its poles.
Mars
The inner planets such as Mars, Earth or Mercury. these are too small to identify in other systems and too close to the star.
Planets are considerably smaller than their parent stars, also they emit no light and are very close to the star. With all this combined, separating between the two with a telescope is very difficult.

It is larger than the planet mercury.
You can see Solar Flares in the Suns' Corona.
The Sun is located in one of the foci [plural of focus] of the Earth's elliptical orbit.
That it is Saturn's biggest moon and it has an atmosphere.

The atmosphere of the gas giants is usually made up of mostly of hydrogen and what?
venus :)
Pluto has a moon that is about half its size
The side of the moon that we can never see from Earth is often called the "dark side" (a) because it sounds cool, and (b) because darkness is a powerful metaphor for the unknown. In fact, the so-called dark side of the moon is not really dark. Luna has day and night on every part of its surface (just like Earth, only Lunar days are 28 Earth days long). During a new moon, for instance, the "dark side" is flooded with light.
The far side of the moon is dark in the metaphorical sense, in that we never see it. To people who think visually (most of us), lack of information seems like darkness.
How is it that there's a part of the moon we never see? Like many moons of planets in our solar system, our moon, Luna, keeps one side to its primary continually (there's a little wobble, so we can really see about 55% of the lunar surface). The moon is "tide locked" (read about tidal locking on wikipedia). This situation develops with all moons and planets over a long time. The Earth's rotation is slowing, too, and will eventually become tide locked to the sun (not for a very, very, very long time, but scientists can measure the tiny lengthening of the day).
Quibble: to be fair, the far side of the moon does receive less light than the rest of the moon, because it doesn't see any of the sunlight reflected from the earth. So technically, it is a bit darker overall. But nearly nobody who uses the phrase "dark side of the moon" is thinking of it in this way.
