Here in our Solar System, we only have one star: a singlet. For many systems, including the highest-mass ones, that’s anything but the norm.
Humanity once thought our Solar System was typical.
The other stars, presumably, were Sun-like objects, but very far away.
We soon learned that stars and stellar systems varied tremendously.
Individual stars come in many different masses, temperatures, and colors.
While our Solar System has just one star, half of all stellar systems have multiples.
Surveying nearby stars reveals that 48% of them are bound in multi-star systems.
But what about the heaviest, most massive stars of all?
They’re too short-lived to perform an accurate census of them.
