I've been fretting about Hip 114110, 15 ly from the Sun, which doesn't seem to correspond to any star in other catalogues. Now I find http://astro.estec.esa.nl/Hipparcos/catalog-errors.html indicating that it doesn't actually exist.

Interesting star HIP 114110 is of class "?5 V" with .01 Sol Radii and a surface temperature of 8200K, the statistics are much like those given for HIP 21088. Possibly it's suposed to be a white dwarf. I see that HIP 114110 is very near to HD 218251, a class G5 V star, with an unbelieveably small radius of .07 Sol and ap absolute magnitude of 10.82. The seperation is 142.474 AU. Both Stars are particuarlly unusual, most noteablly because HIP 114110 isn't real anyway ^_^.

Cheers.

HD 218251 is HIP 114113, which seems to have been the source of scattered light that created the illusion of HIP 114110. The parallax of HD 218251 is too high in Celestia, I'm guessing because it was flagged as being in association with HIP 114110, which had an apparent high parallax. Being too close, its calculated absolute magnitude got very low, so its calculated radius was driven 'way down, too.
