Stephenson 2-18, is a red supergiant star that is one of the largest known stars in the universe
TON 618 is still considered one of the largest black holes in the known universe:
Mass: TON 618 is estimated to be 40–66 billion times the mass of the Sun. This is more massive than all the stars in the Milky Way galaxy combined.
Size: TON 618's diameter is about 30–40 times that of our Solar System. Its event horizon is large enough to fit over 30 solar systems. - From BBC Sky at Night (https://www.skyatnightmagazine.com/space-science/ton-618 )

Kick in to the DU tip jar?
This week we're running a special pop-up mini fund drive. From Monday through Friday we're going ad-free for all registered members, and we're asking you to kick in to the DU tip jar to support the site and keep us financially healthy.
As a bonus, making a contribution will allow you to leave kudos for another DU member, and at the end of the week we'll recognize the DUers who you think make this community great.
