What are those planets surrounding Beerus’s planet?

I’ve had this question for a long time, but I don’t think it’s ever explored in the shows. There’s that one time in dbs when Whis gives Beerus wasabi and he destroys a planet after freaking out over the spice. Which is when whis knocks him unconscious. Which signifies they have some sort of importance. Then, he did it again, but with a sneeze! So, people, make it make sense. Just what are they? , and what’s their purpose?
