    Would someone write this Wikipedia article?

    Wikipedia has lists of stars by proximity out to 75 light years.
    Except for a gap from 16.3 to 20 light years:

    Would it be possible for some astronomer out there to fill in this nasty, annoying glitch?

    Why not do it yourself?

    Here's a list of stars within 20ly:
    http://www.solstation.com/stars/s20ly.htm

    Just remove any that are closer than 16.3.
    Or better yet, add all the appropriate lists:
    0-10, 10-15, 15-20.


    Sure, there'll be lots of missing info, but what better way to motivate someone to fix it?

    I know. Here is another to 25 LY:

    The problem is that I am not very good at editing even simple text in Wikipedia, and hopeless at doing tables.

    I feel your pain.

    Still... can't hurt. You may find some kindred spirits coming out of the woodwork to your aid.

    Another source for nearby stars is the RECONS site at http://www.recons.org/

    They're attempting to characterize all of the stars within 10 pc (32.7 LY) with an extension to 25 pc. They estimate that at least 90% of the stellar systems closer than 10 pc (317) have now been identified.

    If you want to create a new list, just copy the source of one of the existing pages (for example, the 20 to 25 ly list) into your sandbox and modify it appropriately. There are tutorials on creating tables, but you should be able to get most of what you need by reusing the table from that page.

    Note that RECONS hasn't updated their list of the nearest stars in 6 years. It's not that the data there is wrong, but there've been discoveries that it doesn't have.

    I agree they should update their master lists more often. However, their publication page at http://www.recons.org/Publications.htm includes a 2018 paper which seems to include appropriate additions. See TSN44: RECONS Discoveries within 10 Parsecs (Henry et al.) at http://www.recons.org/published44.pdf
    Abstract

    We describe the 44 systems discovered to be within 10 pc of the Sun by the RECONS team, primarily via the long-
    term astrometry program at the CTIO/SMARTS 0.9 m that began in 1999. The systems—including 41 with red
    dwarf primaries, 2 white dwarfs, and 1 brown dwarf—have trigonometric parallaxes greater than 100 mas, with
    errors of 0.4–2.4 mas in all but one case. We provide updated astrometric, photometric (VRIJHK magnitudes),
    spectral type, and multiplicity information here. Among these are 14 systems that are new entries to the 10 pc
    sample, including the first parallaxes for 9 systems and new values for 5 systems that had previous parallaxes with
    errors greater than 10 mas or values placing them beyond 10 pc. We also provide new data for 22 systems known
    to lie within 10 pc and 9 systems reported to be closer than that horizon but for which new parallaxes place them
    further away, bringing the total to 75 systems. The 44 systems added by RECONS comprise one of every 7
    systems known within 10 pc. We illustrate the evolution of the 10 pc sample from the 191 systems known when the
    final Yale Parallax Catalog was published in 1995 to the 317 systems known today. Even so close to the Sun,
    additional discoveries of white, red, and brown dwarfs are possible, both as primaries and secondaries, although we
    estimate that at least 90% of the stellar systems closer than 10 pc have now been identified.
