Plump Mrs. Martian Voted Every Ninth Unicorn Should Jump.
Comments: Pluto isn't a planet now, of course.
Personally, I find that mnemonic hard to remember!
This may help: notice how 5 of the planets have this order: Venus, Earth, Neptune, Uranus, Saturn. The first letter of each planet spells "Venus".
You can easily make up your own mnemonic. The trouble is Mercury and Mars begin with "M" so you need a way to distinguish between them.

Mercury is the answer. The inner planets in order from greatest to least density are: Earth Mercury Venus Mars
Mercury is the answer. The inner planets in order from greatest to least density are: Earth Mercury Venus Mars
Mercury, Mars, Venus, Earth, Uranus, Neptune, Saturn, Jupiter.
Two planets are at their greatest separation when they are on opposite sides of the Sun. When a planet is at its greatest separation from the Earth the planet is said to be at superior conjunction. It cannot be seen until it has separated out from the Sun, which usually takes a few weeks at least.

The gas planets, in our solar system at least, are Jupiter, Saturn, Uranus, and Neptune, in order from least to greatest distance from the Sun. They are all found beyond the Asteroid Belt. The gas planets, or "Gas Giants" if you will, are larger and less dense than the other planets. They all have rings and several moons.
