Wtf, they probably changed the naming convention. Original asteroids database in SE (Asteroids.sc, Asteroids-small.sc etc) is made by processing a catalog file downloaded from MPC. This was many years ago though. Maybe all asteroids in SE should be updated to the new naming?

I can confirm that MPC is still using the naming convention we are using now, in fact my data came from their database.

It seems that both naming conventions are used.
That's why I used the first name without parentheses and the second name with parentheses. But only if I found the name in the sources like that. For example, Wikipedia. If I found only the first spelling of an asteroid, then not. (That may be inconsistent.)
Maybe this spelling should be used:
"Name/Number Name/(Number) Name/<other designations>"

Seems good. But all asteroids what are already in SE must be updated. Maybe someone can make a Python script?

A simple regex in notepad++ like find
/\((\d*)\)(\s\w*)
and substitute with
/\1\2/\(\1\)\2
does the trick.

edit:
Oops, I forgot there are catalogued asteroids without an official name like 2001 FA70
also, "Lempo/(47171) Lempo/1999 TC36 A1/(47171) 1999 TC36 A1"

There's a small error in the name of M43 nebula, De Mairan's nebula is written "De Marain's". This is the code for correction:
Remove "De Marains Nebula" { ParentBody "Milky Way" }

Nebula    "De Mairan's Nebula/M 43/NGC 1982"
{
    Galaxy  "Milky Way"
    Type    "Diffuse"

    Dec     -5 15 22.68
    Dist     428
    Radius   0.4

The Ross 752/Wolf 1055 system has an additional star in the center of the system.
scr00661.jpg
This is because the star has more names in 'Hipparchos.csv' than in the newer 'BrownDwarfs-bin.sc'. (Discovered by 'Platinum Hero' on Steam.)

I made a fix for it.

Currently in SpaceEngine, Mars' moon Deimos has a density of 16.386 g/cm[sup]3[/sup]. On closer inspection, this appears to be an error with the asteroid's mass.
scr00079.jpg
I have created a small fix to decrease its mass and bring its density closer to it's real value.

And as a side note, when making a planetary system, you can use the System Chart to see if everything has accurate properties, such as temperature, density, and system architecture.

Gliese 688 is a double binary located ~35 LYs located in the constellation of ophiuchus. The A component is a K class orange main sequence star with an estimated radius ~84% of sol. In SE however due to a typo its radius is 840% of sol. Here is the corrected catalog file - to be extracted inside addons directory. However I don't know why but the star now appears much brighter with a much greater halo/corona in the preview icon as presented in star system browser. I don;t know as to why this is happening. Any help would be greatly appreciated as I am no expert in this. Thank you for your understanding regarding this far from perfect correction.

The Star HIP 51436/HD90983 appears to be a "K5 V" type star while it´s brightness is beyond 21000 times the sun, this star would be a Orange Giant class "K5 III", I changed the star class and included the exact same values that Space Engine did, except the class, the simulator regenerated the temperature, size and mass and also I think the brightness too.

The temperature (between 3500K-5000K) of the star and the solar radius vary between 372.73 to 869.79 times of the sun according to this page:

HH 6819 is currently listed ingame as a triple system with one of the three being a black hole. Recent further studies using the ESO's Very Large Telescope and accompanying Inferometer appear to have concluded that there are only two stars, in a wider orbit.
