Star Catalogs within 200 LY of Earth - Needed in Table Format

Click For Summary
SUMMARY

The discussion centers on the challenge of obtaining star catalogs for stars within 200 light years of Earth in a table format, specifically .csv. Users are directed to resources such as the Wikipedia list of the nearest stars and the VizieR database for astronomical data. It is established that compiling a complete catalog is nearly impossible due to the vast number of stars, many of which are too faint to observe easily. The discussion emphasizes the limitations of current astronomical equipment in determining precise distances for these stars.

PREREQUISITES
  • Understanding of astronomical concepts such as light years and stellar magnitude.
  • Familiarity with data formats like .csv for tabular data representation.
  • Knowledge of astronomical databases, specifically VizieR and USNO-B1.0.
  • Basic skills in data manipulation and extraction from online resources.
NEXT STEPS
  • Research the capabilities of VizieR for filtering star data based on specific parameters.
  • Explore the methods used in astronomical surveys for determining stellar distances, including parallax measurements.
  • Investigate the limitations of current astronomical equipment in observing faint stars.
  • Learn about the significance of stellar magnitude and its implications for visibility and observation.
USEFUL FOR

Astronomers, astrophysics students, data scientists working with astronomical data, and anyone interested in compiling star catalogs for research or educational purposes.

I am looking for star catalogs of stars within 200 lys of Earth for a project I am working on. I would like to have them as .csv, but any table format should do. I'll need such info as name, dist, mass, luminosity, spectral type, galactic coords or RA and Dec., radius. So far my attempts at google is a search overload and what I have found are not in table and cannot be copied easily.

Any help is appreciated.

What you're asking for is pretty much impossible. See this list for the nearest 50:

http://en.wikipedia.org/wiki/List_of_nearest_stars

A lot of those stars are magnitude 17, and one of them is magnitude 22. To give you an idea of how many stars are that dim, take a look at this photo:

http://www.distantsuns.com/screen_shot6.html

The faintest star there is only magnitude 16, two times brighter than magnitude 17 and 200 times brighter than magnitude 22. The entire chart covers a region roughly equal to the area covered by your thumb at arm's length. To find all stars within 200 light years, astronomers would have to look at every single one of those stars and determine whether its distance: an impossible task. Even photographing all those stars takes years of work, and to determine distance you'd need to take photos separated by six months to look for parallax. I don't know if any of the sky survey equipment can determine a star's position to within 20 milliarcseconds (the parallax at 200 ly), but I'll be really impressed if they can.

So, I don't think what you're asking for exists, or will exist any time soon.

There are 39 stars within 15 light years of earth. That means one would expect 39 x (200/15)3 within 200 ly. That's about 100,000 stars - which is a lot. Worse, most of these stars are, as ideasrule mentions, practically invisible.
