Looking For Galaxy Dataset Containing Celestial Object Location For A Snapshot In Time

Hi, I’m looking for a space dataset about a specific galaxy. Any galaxy will do. It needs to have spacial information for each celestial body (planet, star, black hole) for a snapshot in time, so I’m thinking an x, y, z value. I want to know each object’s location in the galaxy. It would also be nice if the dataset contained what each object is (star, planet, black hole). It could also go into more specifics about the class of the type of object it is like dwarf star, gas planet, etc & the size of the object or its radius. I’m planing on using this dataset for an art project for one of my classes. Thank you.
