COMMUNITY ADDON - Double/Multiple Asteroids fixes for SE

I see, Asteroids-Rem.sc was for those using SE v.0974, better if I remove it, it's only confusing at this point.
In your case you may delete your Asteroids-Rem.sc.

Ok, thanks. But what about  objects like 2003 QW1112007 TY430?  Thay are now named so there would be duplicates without Rem.sc, or would there be?

I did also discover that the moon of (2006) Polonskaya is named in SE as S/2005 (2004) 1! I would suggest you to fix it when you have time.

Just found out the largest TNO thought to be moonless, 2007 OR10, indeed has one, and it isn't in SE, so here's a quick script. (It does count as a binary, right? Idk, but I guess it's close enough.)

I did already post about the moon 2007 OR10 and Sisyphus but I do not think Mosfet has published it yet. It was based on data from http://www.johnstonsarchive.net/astro/a ... moons.html

No, there should be no duplicates. If you look at Asteroids-bin.sc for 2003qw111 there's a "remove" command right above the barycenter Manwe-Thorondor:
Remove "2003 QW111" {ParentBody "Sol"}
Barycenter "Manwe-Thorondor"
[...]

This tells SpaceEngine to ignore the existing object 2003 QW111 loaded from previous scripts.

(2006) Polonskaya companion will be fixed in next upload, thanks.

It does indeed :) I'll add them soon.

Thanks, I did found this to be true for 2007 TY430 (Mors) aswell, so there should be no problem. Just one thing I wasnt to ask you. I did realize the SpaceEngine "SolarSys.sc" 0.981 had discovery dates and method displayed for Uranus, Neptune, many moons and Pluto + Charon.

I did realize that if this info is displayed on these objects sure should it be the others as well and I did add discovery info on the rest of Dwarf planets + Dysnomia and Vesta, Pallas and Hygiea. I did also fix problems and typos in these files.

After this I did go through all the named Solar asteroids included in SE and added the same information on them. I did not touch "Asteroids-bin.sc" however would you mind if I would add this information on your file for named bin asteroids + their named moons or you could do this yourself after its next update is finished?

You can go and see my files in 0.981 beta test thread if you wish Mosfet. Since if I remember right you have access to it.

Example from SolarSys.sc:

Moon "Ganymede/Jupiter III"
{
ParentBody     "Jupiter"
Class          "IceWorld"

DiscMethod     "Imaging"
DiscDate       "1610.01.08"

Mass            0.0248
Radius          2631.2

Planet "Uranus"
{
ParentBody     "Sol"
Class          "IceGiant"

DiscMethod     "Imaging"
DiscDate       "1781.03.13"

Mass            14.536
Radius          25559
Oblateness      0.02293


Example of my additions in SolarSys.sc:

Asteroid "Pallas/(2) Pallas"
{
ParentBody     "Sol"

DiscMethod     "Imaging"
DiscDate       "1802.03.28"


Mass            0.0000345
Radius          263


Examples I added to Asteroids.sc, Asteroids-small.sc, KuiperBelt.sc, KuiperBelt-small.sc and Comets.sc:

Asteroid "Astraea/(5) Astraea"
{
ParentBody "Sol"

DiscMethod     "Imaging"
DiscDate       "1845.12.08"


AbsMagn     6.85
SlopeParam  0.15

Asteroid "Europa/(52) Europa"
{
ParentBody "Sol"

DiscMethod     "Imaging"
DiscDate       "1858.02.04"


AbsMagn     6.31
SlopeParam  0.18

Asteroid "Pholus/(5145) Pholus"
{
ParentBody "Sol"
AsterType  "Centaur"

DiscMethod     "Imaging"
DiscDate       "1992.01.09"


AbsMagn     7.1
SlopeParam  0.15

Asteroid "Varuna/(20000) Varuna"
{
ParentBody "Sol"
AsterType  "Cubewano"

DiscMethod     "Imaging"
DiscDate       "2000.11.28"

Radius      450

That's cool! When you'll post your modified Asteroids-bin.sc here, then I'll update it in OP.

Thanks, I will do this, but it will take some time. I have also been adding new TNO:s to KuiperBelt-small file to make it more complete. 

(Edit. It will still take some time to finish all discovery date additions for binary asteroids/TNO:s but I have been doing it for quite while already.)

I have finished adding the discovery times of binary asteroids/TNO:s and their moons. I did add the dates for named objects and those objects that were known as "beta", "gamma", "A", "B" or something similar. I did also fix the typo on moon of Polonskaya, named Hektor's moon and added the "|" symbols as they will be needed in next SE version.

However I did have problem with (47171) 1999 TC36. I think there might be an error there because the catalog says largest object in this triple system is "1999 TC36 A2". Shouldnt the largest compont be A1 instead of A2? I was not entirely sure which object was which, so could you add their discovery dates plese?

Also were you going to add the moons of 2007 OR10 and Sisyphus as the data was already presented on this thread. Could you also add the second ever discovered TNO binary 1998 WW31 and S/2000 (1998 WW31) 1? The primary is already present in SE but its moon is missing.  

Sisyphus moon:

Hello! Do you consider adding the moon of TNO 1998 WW31 soon or have you already added it? As it is a true binary system with two nerly same sized bodies (148 km and 123 km, diameter ratio 0.833) orbiting around one another I do not know how can I calculate the orbit of the primary around the mass center / barycenter to write the information on this object to the files as I did with Sisyphus.

It's been added in the last update :) . Whenever I update Asteroid-bin.sc I also update the list of asteroids contained in first post. Since 1998 WW31 doesn't appear to have a designation number yet, it's listed in "Others" category in that post.
