I don't often know where to start with worldbuilding.
Artefexian takes astronomy first when worldbuilding, particularly stars first, then planets, then moons.
I did his Build 1000 stars and I had to keep adjusting the measurements for the 1 solar mass stars to 1 in relation to the sun
I did lowest mass first for each spectral type to be safe.
The planets are what trouble me here. I can't easily look up minimums and maximums for different types of planets such as mini neptunes vs super earths vs hot saturns vs dwarf planets.
And for those I need mass, radius, density, and distance in AU to the star or stars and from those I can deduce the orbit properties.
I also can't easily figure out relative gravity(how much more or less gravity an astronomical body has compared to earth) and physics is my least favorite science.
So this means that exact composition of solar systems for me is practically impossible. However I know that red dwarfs are more likely to have 1 and just 1 planet and F type stars are most likely to have lots of planets and all stars in this range are outside of the mass range for type 2 supernovas. Type 1s can still occur though.
Because of this, I don't usually get to solar system level worldbuilding, much less star clusters.
I usually instead start with a single planet and get into more detail about that 1 planet. However in my story about humans living with dinosaurs, I will have lots of astronomy in the chapters about the trip from earth to this other planet.
Usually this astronomy is scattered with the rest of what the humans learn. Like for example the computers might say Warning, Supernova. The aliens would need to know whether it is going to form a black hole or a neutron star or eject 1 or more stars and change course accordingly. The humans would have to huddle together under sturdy structures. Then afterwards the aliens would teach the humans about supernovae, neutron stars, and black holes and the normal day/night cycle on the generation ship would continue.
Anyway, when they get to the solar system with the planet that has dinosaurs I will have to do astronomy level worldbuilding. But once again I can't find minimums and maximums for a lot of planet types. However I need these minimums and maximums, otherwise I could have a 15 earth mass, 2 earth radius, neptune-like planet and consider it a mini neptune according to radius. However this does not make sense at all since neptune's density is way lower than earth's density and at 1 jupiter mass(same as 15 earth masses) and 2 earth radii, the planet would be extremely dense and most likely be a pure iron planet.
