Astronomy - Star Catalogue

[dekoi]

I need to access a star catalogue on the internet that will tell me the distance of the stars from earth, as well as the mass of the stars.

I need to "find" 2 stars:
approx. 346.7 pc from Earth
approx. 0.4786 pc from Earth

I realize that there may be none. However, the point of the assignment is to find these values for a supernova, and then determine whether there is ACTUALLY a high-mass star that close to Earth that can one day explode as a supernova.

Thank you for any help you can provide-- whether you know the answer, or you know of a catalogue of the type specified.

You get distances from almost any decent catalog, e.g. Hipparcos. I don't know of any catalogs which directly include mass, since mass is a relatively challenging quantity that cannot be determined (as of yet) by a highly-automated satellite observatory.

Here's a good list of the most common star catalogs:

Is there an on-line catalogue? I don't think those are on-line.

Thanks.

Almost every catalog listed there is available in its entirety online, as they were created with public funds and are considered public information. Most of them even have online search tools, publicly available.

Come on, dekoi. Read the page. Click the links. Use google.
