Who is Sirius B?

Sirius B is a tiny, super-dense star that lives far away in space, like how your favorite toy has a tiny but strong friend hiding inside it.

Imagine you have a soccer ball made of regular stuff. Now imagine a soccer ball that’s as heavy as a big truck, but it's the size of a cherry. That’s Sirius B, super heavy, but really small!

Even though Sirius B is tiny and far away, we can see its effects on its bigger neighbor, Sirius A, which is much brighter and easier to spot in the sky. It's like how a little kid can push a big kid around on a swing, you might not see the little kid, but you feel their effect.

Sirius B is so dense because it’s made mostly of white dwarf stuff, imagine it’s like a super-compressed version of a star. It's been through a long journey in space, and now it's just sitting there, tiny but powerful, watching over its bigger friend.

It's not magic, it's just how stars work! Sirius B is a tiny, super-dense star that lives far away in space, like how your favorite toy has a tiny but strong friend hiding inside it.
