You have to accompany for many factors. A planet can be closer or further away than us depending on it's size and atmosphere, and still support life. Furthermore, the size of the actual sun. Depending on the star's output of heat, you can have a planet pretty far away and still support life.
I'm not even going to go into the necessities for actual life, but ultimately, it's just a throwaway line that doesn't change much. It doesn't make any sense, no, but it doesn't really hurt the scene or the show.
Though, seriously, the possibilities of Planet Vegeta, or anywhere else, having the same hour/week structure is pretty ridiculous.
