As already written at the beginning of December, I have been looking for star catalogues in the past few months that contain as many objects as possible in the immediate vicinity of our solar system. With the exception of exoplanets, which don't interest me at first.
I found a star catalogue with 120,000 entries, which is regularly updated. However, it only lists "real" stars, roughly speaking 80 Jupiter masses and more.
Everything that is smaller and flies around between these stars, it does not contain. This includes the oddballs of our galaxy, brown dwarfs and free-floating planets that don't really fit into any category.
Them I found in another database, extracted them and made the result available for download in a specially created, separate catalogue. 869 objects that most people don't even know exist. But it is precisely this Twilight Zone of celestial objects that I find tremendously fascinating. Don't ask me why.
For more information, see Download - RISSO Catalogue.
