New Namek
The new namek was created after all the namekians were brought to earth. They wished for a new planet in the solar system. That namek is similar to the old namek. It is never night there and has a lot of vegetaion.

Planet Freeza 79
One of Freeza's many planets. This was the headquarters of Freezas armies and where he usually makes his plans.

Kanassa
This planet is seen during the Bardock Special. It is inhibited by fish like beings who had pshychic ability. Bardock and his group went Oozaru and destroyed all the beings on the planet and made it part of Frieza's empire.

Meet
Another planet seen during the bardock special. Frieza ordered Bardock and his team to take over the planet. When they got there, the entire team except bardock were killed by Freeza's henchmen. Freeza had began to worry that the saiyans would rebel.

Vegeta
The home planet of the saiyans. It was home for two races, the saiyans and the Tsurferans. They both co operated with each other until the Saiyans destroyed them. Frieza eventually took over the planet and made the saiyans his slaves. Eventually, the saiyans wanted to rebel, and Freeza was scared that a saiyan would rise up and kill him, so he destroyed the planet.

Yardratt
Before Old Namek was about to explode, Goku found the Ginyu Forces' pod. He used that and escaped. The pod took him to yardratt. When he got there, he was knocked unconscience. The people there helped Goku and they taught him the instant transportation technique. The people from Yardratt then fixed Goku's ship and sent him home to earth. Yardratt is also where Goku caught his deadly heart virus.

Planet of Darkness
This planet is in the far corner of the universe. There are no stars close by so it is always dark there.

Zun
The gravity here is ten times that of earth. It is very dark and cold here.

Snake way
Snake way leads to King Kai's small planet. Usually, dead warriors end up here and have a seperate journey here. If you fall off of snake way, you end up in hell.

King Kai's Planet
This planet is located at the end of snake way. There, King kai, his monkey bubbles and student Gregory reside. The gravity there is 10x the gravity of earth even though it is a small planet. It was destroyed when Goku teleported with Cell who exploded.
