My Very Easy Method Just Speeds Up Naming

I think of them more as by properties: Mercury hasn't even an atmosphere, it's too close to the sun; Venus is a hot earth so it sits closer than us; then comes its sister planet Earth; Mars is cool by comparison and sits further away than we do. Jupiter and Saturn are harder but sit before the ice giants Uranus and Neptune, again making logical sense. Whether Jupiter or Saturn comes first, I guess there's some memorisation, with or without some sentence about it
