The Kuiper Belt object (208996) 2003 AZ84 appears to be shaped like an ellipsoid with the dimensions 940 × 766 × 490. There's a recent paper regarding its shape: https://arxiv.org/abs/1705.10895

JD, what are planets 5a and 8a, I've never seen anything like that before! Procedural double planets? I wonder if there are any anywhere in reality! So this is a real star but no real planets have been discovered around it?

This is new in SE 0.990. This is the new designation for binary planets.

Thanks, JD! These are all procedural planets correct? Are any actual binary ones included?

These are all procedural planets.

When I was playing with regular expressions in Notepad++ in order to add/remove brackets and things alike, I noticed that some objects in stars and planets have what appears to be syntax errors in their constellation names, wrong caps to be precise. This is a list:

\Catalogs\stars\ExoPlanetsSuns.sc
    Line 348: Star    "8 UMi/8 Umi/HD 133086/HIP 73136"

    Line 7985:     ParentBody "TAU Cma"

where Uma, Cma, Umi, should instead be UMa, CMa, UMi.
I googled around to check if that could have been accepted nomenclature too, but I haven't found material about it.

Septuple star systems Nu Scorpii appears as a quintuple system while AR Cassiopeiae is not present in SpaceEngine. There isn't much information about their orbits, which might complicate things a bit.

I already added NU Sco to SE, but didn't worked on AR Cas yet.

Thanks, fixed. Implementing BB codes for Greek letters and constellations will solve all such errors, because BB-codes are not case-sensitive.

Does that have procedural planets?

N3cronium · 16 Jan 2019 17:30

There are no procedural planets around the stars.

0980 here: Comet 46p/Wirtanen has a diameter of ~ 1.4 km (according to Wikipedia). In game it has a radius of ~6.something kms.
I opened catalogs0980.pak but the comets.sc file only had its magnitude characteristics? How do I correct its size??
