Mass in seconds? How? I get mass in Joules, but seconds?

Size doesn’t say much about mass though.

I thought stars of similar masses were also of similar sizes. They’re not?

I’m no astrologer but from what I’ve learned, we also need to look at the color to glassify stars into categories. It varies a bit though in each category so it’s a blunt tool.
Then there are other objects like gas clouds and even galaxies. For those, we have no idea of the density distribution, so radial size gives us even less info.
