Planet Kanassa (now Freeza Planet 419) is the home of Tooro and other Kanassans. They were wiped out by Bardock and his henchmen, but they somehow repopulated themselves sometime after that.
It's been stated by Vegeta that no one ever goes to Freeza Planet 419. This is likely due to their massive population of Kanassans all screaming (accurate) predictions of the future randomly; which have been compared to YouTube comment sections. Such predictions include:
- Bulma and Vegeta have a kid.
- The real Buu is a child.
- Cell reaches his perfect form.
- Goten and Trunks become a guy.
- Gohan is the strongest in the universe, but still doesn't do craaaap.
- In the NES game, Goku indeed goes there and makes the planet belonging to the Kanassans again
