There are a couple of issues with stars in-game that are treated in one part of the catalog as binary stars, and in another as a star-exoplanet pair. This leads to things like barycenters showing up as duplicates of a main star. Go look at Keid for one example, where what should be a trinary star system is instead a quaternary star system as the barycenter has suddenly become a star.

I searched through the catalogs to find stars that share the same name for both a StarBarycenter and a Star, and then checked them in-game, and fixed the ones that were doing this. This should resolve these issues. Place it in your addons folder, or download the attached .pak file:

HIP 66892/HD 119445, a star with a known brown dwarf companion, has an apparent magnitude of 2 when seen from Earth in SE 0.990. This makes it as bright as the stars in the Big Dipper, and it looks like an extension of the "handle".

Even though HIPPARCOS.csv gives its distance as 289 parsecs, something is resetting the distance to 19.3 parsecs, but I haven't figured out what it is. This script reasserts the same data as its entry in HIPPARCOS.csv:

StarBarycenter "HIP 66892/HD 119445"
{
    RA      13.7080203
    Dec     41.6742541
    Dist    289.017317

This is probably because the star is not only in the Hipparcos catalog, but also in the 'BrownDwarfs-bin.sc'. There, however, the distance is missing.
The 'BrownDwarfs-bin.sc' catalog overrides the Hipparcos catalog. Therefore, SpaceEngine creates the distance itself. (I have no idea what kind of algorithm SE uses for this.)

The double asteroids 'Manwë-Thorondor' and 'Varda-Ilmarë' are already in SE. Likewise 'Sauron'. Otherwise I would have added them too.

This thing baffled me too, but that's how it is in Minor Planet Center and other sources too.

Actually, the asteroid Mr. Spook is not named after Spook from Startrek, but after the cat of the discoverer! This cat, however, was named after Spook from Startrek. (From the German Wikipedia.)

JackDole, your naming of asteroids is inconsistent. I propose to follow the convention used in SE:


Bilbo/(2991) Bilbo/<other designations>


This will make is easy to find asteroid in the F3 menu by fancy name "Bilbo". For those who know the number, typing "(2991)" will also show asteroid in the list. "(Number) Name" is a conventional naming of minor bodies.

The first name I give to the asteroid is the name under which the asteroid appears in the 'JPL Small-Body Database'.
Billbo.png

If the number is in parentheses, the database will not find the object.
But in future I will only use the name without number as the first name.
