The four inner planets are also known as the terrestrial planets (or the `rocky` planets). These are; Mercury, Venus, Earth and Mars.
The inner system is Mercury, Venus, Earth and Mars. The inner system is all rocky planets because gas giants like Jupiter will "Melt" under that kind of temperature.
Because when they are close to the sun first of all they are are smaller so if they had a moon the moon would have to be kinda small. And also the planets close to the sun are made to be able to get to high temperatures. Earth can't get satellites to Mercury and a moon is related to the satellites and the moon would burn up in the heat. All mass has gravity. The inner planets cannot "hang on" to their moons due to their lack of mass, therefore they are unable to overcome the suns gravitational affect on the moons which would pull them into the sun. The outer planets can "hang on" to their moons and attract more because of their mass (therefore gravity). The distance from the sun has less of an impact on these moons, therefore, the sun cannot pull any of the moons away from the outer planets. Also, the outer planets are "kind of" moon magnets due to their gravitational pull.
Well, honey, the inner planets are called terrestrial planets because they are rocky and solid, just like your ex's heart. They are closer to the sun and have similar characteristics to Earth, unlike those gas giants that are just full of hot air. So, basically, they are named that way because they are Earth-like, but without all the drama.
Mars and Earth are both rocky or "terrestrial" planets. Mars and Earth also belong to the group of inner planets (along with Venus and Mercury). Inner planets are in front of the meteor belt (between Mars and Jupiter), outer planets are behind the meteor belt.
Dwarf Planets.
well the gasses in planets are hydrogen,methane and helium
Inner beauty is beauty within yourself. A nice kind-hearted person has inner beauty.

Saturn, Jupiter, Uranus, and Neptune are the outer planets and are also gas giant planets.
