Source of the post How do I correct its size??

Make a new script for the asteroid and save it in 'data\catalogs\planets'. If the folder does not exist, create it.
You can also save it in 'addons\catalogs\planets', but I prefer the 'data' directory for corrections to catalog objects.

SpaceEngine calculates the size given other elements, that's why there's no "Radius" value.
You can add it as JackDole said, in a 46PWirtanen.sc file, for example like this:

Comet    "46P Wirtanen"
{
    ParentBody "Sol"
    CometType  "P"
    AbsMagn     9
    SlopeParam  6
    Radius      0.7
    Orbit
    {
        Epoch            2456482.8987
        PericenterDist   1.05208
        Eccentricity     0.659288
        Inclination      11.7572
        AscendingNode    82.1633
        ArgOfPericenter  356.343
        MeanAnomaly      0
    }
}

SE then will use that file as reference for that object next time you run SpaceEngine.

Thank You JackDole, Mosfet,

The star S0-102 appears too close to Sagittarius A* since the procedural semi major axis is around 4.5 AU. The semi-major axis of S0-102's orbit is not specified in the script and should be around 260 AU or more.

Neptune XIV has been finally given the name Hippocamp! All of Neptune's moons have names now, here's a script adding Hippocamp's new name and refined orbit.

Remove "Neptune XIV" {ParentBody "Neptune"}

DwarfMoon   "Hippocamp/Neptune XIV/S|2004 N1"
{
   ParentBody     "Neptune"
   Radius          17.4
   Albedo          0.09
   Brightness      0.74 // supposedly dark

   Orbit
   {
      PeriodDays      0.9362
      SemiMajorAxisKm 105284
      Eccentricity    0.00048
      Inclination     0.0641
   }
}

I know this is a minor error, but I'm just going to point it out.

There's a binary system named SDSS-J080531.84+481233.0
However, in reality, the SDSS catalog uses a space between "SDSS" and "J", NOT a "-"

This star is indeed very close to Sgr A*. Its SMA is not known, but using knows period (11.5 years) and mass of the Sgr A*, SE calculates SMA = 829 AU.

It was formerly known as Polyphemus... Ok, I renamed it in the catalog.

Thanks, fixed!

Hi ! I have recently used Space Engine 0.98 with the patch (sorry for my bad English). I don't know if this has already been said. I am concentrating on the solar system and I have found errors in the data of the planets, for example axial inclination, period etc (I am not checking the atmosphere, only physics and orbit). The time of the pericenter does not correspond with the date and time of the PC. It does not include the time zone in the watch. Thank you very much

The planet "WD 0806-661 B b" shouldnt be a very dim planet, it should be a Y-Type brown dwarf.

The planet "KOI-3891.01" is apparently 2 AU in diameter in SE 0.980, and due to that diameter, makes its parent star be inside the planet, and for some reason, the planet's textures flash/glitch.

SpaceSpade · 06 Jun 2019 11:36

This red dwarf (OGLE-2005-BLG-390L) had a diametre of 0.19 AUs, which is wrong for these stars, in fact even the Pollux' diametre is about 0.07 - 0.09 AUs. There is also its planet's addon, which features some orbital changes in order to prevent the planet becoming an ice world after decreasing the star's size. Now about this major bug that Soldies502 found. I made an addon too.
Edit: I decided to change the last planet from ice giant to an oceania because of the diametre and because it is a chtonian class planet (a scorched superfluid water planet, a gas/ice giant remnant).
Eh, and I also found another bug after editing. There was no surface after editing a planet. I did not touch surface settings.
Welp, sorry, I had to change it back to an ice giant (minineptune) because it supports the planet texture only if it is a gas/ice giant texture model. Also I fixed a star model. In reality it is a hot subdwarf, not a yellow dwarf as in the game.

Thanks for fixing

Kappa Andromedae is the wrong color (a very vibrant red) despite technically having the correct B9 IV classification: https://imgur.com/a/Ix5tO3l

Additionally, Charon's discovery date is incorrectly listed as 1678 in the interface despite having the correct 1978 in its wiki: https://imgur.com/Hw9dlOE
