Asteroids for Celestia

[gironde]

new topics for your addons on Asteroids

[Croc]

These are new guidebooks. Themes are Jupiter's name Trojans. Only 253 asteroids. Many asteroids are not in the database. Maybe someone will want to create an additional database of Neptune’s registered Trojans.

[LukeCEL]

I just wanna comment that a lot of the add-ons, including the asteroid add-ons, on the Celestia Motherlode are sadly really out of date. There's not really much we can do about it, though, since most of the creators are no longer active. Also, Art Blos and his team's Celestia Origin project covers a ton of asteroids anyway.

[LukeCEL]

Maybe someone will want to create an additional database of Neptune’s registered Trojans.

Using the Minor Planet Center's List of Neptune Trojans, I was able to quickly create an .ssc file for Neptune trojans. However, the parameters given in the list aren't very precise.

(edit: added the URL to the list itself.)

I made a typo in the message. Should read:

These are new guidebooks. Themes are Jupiter's name Trojans. Only 253 asteroids. Many asteroids are not in the database. Maybe someone will want to create an additional database of Jupiter's registered Trojans.

In addition, I did not explain what the "#" and "?" Signs mean.
I explain that the positions are marked with "#" and "?" , are absent in the asteroid database Project "Celestia Origin", release dated August 30, 2018.
==================
LukeCEL, thanks for the ssc file.
It will be a model for the development of an additional database of Jupiter’s registered Trojans. In addition, I found a source for compiling the ssc-file of the Jupiter Trojans. https://minorplanetcenter.net//iau/lists/JupiterTrojans.html

[LukeCEL]

Maybe someone will want to create an additional database of Jupiter's registered Trojans.

By "registered", do you mean all the Trojans with names? Or do you mean all the Trojans with numbers?

Also, do you want the database to not include any asteroids in Project "Celestia Origin"? If so I might need a list of asteroids that are in the project.

[Croc]

By "registered", do you mean all the Trojans with names?

LukeCEL,

1. I mean only asteroids with names. Such asteroids 253:

2. Positions marked with red squares are in the database in Project "Celestia Origin. There are 48 such asteroids.

3. It is necessary to create additional base 253- 48 = 205 asteroids.

[LukeCEL]

2. Positions marked with red squares are in the database in Project "Celestia Origin. There are 48 such asteroids.

I counted 57 such asteroids in your list...

Also, I think some are misspelled. "Agirhenes" should be Agasthenes, "Agirrophus" should be Agastrophus, "Aliror" should be Alastor, "Atreropaios" should be Asteropaios, and "Atryanax" should be Astyanax.

[Croc]

I counted 57 such asteroids in your list...

I did not include the 6th column. 48 + 9 = 57.
I still found 3 asteroids (blue squares).
The correct number is 57 + 3 = 60!
====================================
I corrected the names of 5 asteroids (orange squares)

Here is the correct list of asteroids:

Okay. Here's the finished product, which has 190 Trojan asteroids. The file does not include Eurydamas, Iphthime, Makhaon, Menestheus, Pandarus, Patroclus, Pyrrhus, and Thoas, and any other Trojans that are included in Project "Celestia Origin".

[Croc]

LukeCEL,

253-60-190=3 asteroids:

• "29314 Eurydamas:Eurydamas:1994 CR18:2000 TR49" "Sol/Eurydamas System"
• "16974 Iphthime:Iphthime:1998 WR21:1974 WX:1986 WS" "Sol/Iphthime System"
• "617 Patroclus:Patroclus:1906 VY:1941 XC:1962 NB" "Sol/Patroclus-Menoetius"

In 3 asteroids the access path was incorrectly indicated, so they were not found by Guidebooks.
===============
LukeCEL, thank you for the excellent work.

[gironde]

In 2017, I modified Lut5's Vidiba module to display asteroids based on their orbit or origin rather than the size of their orbit.
To be used correctly in Vidiba (2), asteroids should only be used in one table, so some are voluntarily excluded from one table for use in another.
In spite of that the table concerning Jovian's trojan contains 7209 asteroids. Some use the ssc file from the work of Art Blos and others a complementary file that I created from the JPL database.

The ssc complementary file is not yet complete compared to the 7209 asteroids of the table. I still have to check the ones I miss. A lot of work !

Note: for their use in Vidiba, asteroids are all able to property 'Visible false', it is the use in Vidiba that makes them visible.

Added after 2 hours 25 minutes:
compared to my table Jovian trojan and my ssc files (At Blos and more Jovian Trojan), it remains to create the scc for 7009 asteroids 'Jovian Trojan'
here is the list

[LukeCEL]

Croc, I recommend updating 3451 Mentor to include this code:

Code: Select all

   Color [ 1.000 0.896 0.817 ]
   BlendTexture true


The color was calculated from its SMASS spectrum (available here) and converted to an RGB value using Matt Wronkiewicz's spectrum2rgb.c utility.

After Jovian trojans here are the NEA asteroids (ECA-MCA):
- ECA : Earth crosser and Earth grazing; families : Alinda, Amor, Apollo, Aten, Atira
- MCA : Mars crosser (8065 + 16212)

ssc files complement those of LUT5 and Celestia Origin. The data comes from JPL.

[gironde]

Now, here are Asteroïds Belt : inner, main, outer

- Asteroids Belt inner :
Flora family
Hungaria family
Vesta family
others

- Asteroids Belt main
Agnia family
Alinda family
Astraeae faùily

Ursula Family
others

- Asteroids Belt outer
Cybele family
Griqua family
Hildas family
Themis family
Thule family
Ursula family

note that some families are riding on 2 groups.
Groups are defined by their location while families are defined by their original formation.

Added after 24 minutes 40 seconds:
here, Asteroïds TNA

- Asteroids TNA
cubewano (Kuiper Belt)
plutino (Kuiper Belt)

others
Planet Nine : asteroids seem to be disturbed by a ninth planet

Added after 30 minutes 30 seconds:
and here, asteroids Centaur : Centaur and Centaur-damocloïd

ssc declarations are in the asteroid files of Lut5 and Celestia Origin; there is nothing to add.

[LukeCEL]

Hello everyone. This is an updated version of the Neptune Trojans add-on I created earlier. Compared to the previous version, it has one additional Trojan (2012 UD185) and updated designations and names for a few of them.

(edit: the new asteroid is 2012 UD185, not 2012 UV177.)

Enjoy:

[SpaceExplorer]

Let's revive this topic after 3 years

Here I will post some asteroid addons, so as not to create new topics. All orbital parameters will be obtained from JPL SSD.

Here's 2022 EB5. It was the 5th asteroid discovered before it collided with Earth. On March 11, 2022, just 2 hours after its discovery, the 2-meter-long rock entered Earth's atmosphere over the Arctic Ocean.

To see it in Celestia, you must set the time before 2022-Mar-11, 21:32 UTC

[EarthMoon]

2 addons:

(16) Psyche
is a large main-belt asteroid between Mars and Jupiter at almost 3AU distance from sun.

The Hildian asteroids
are asteroids on 3:2 orbital resonance with Jupiter.

2021 PB130
My little child

The asteroid in Celestia.

Discovery images in IASC Pan-STARRS data.

Precovery images in public Pan-STARRS images.

2021 PB130 is your typical asteroid in the Eulalia family. Not much is known about it, its dark and generic, and also small. And its in the main asteroid belt too.
So why i'm making this? Because despite what the MPC thinks, i actually discovered this asteroid during an IASC search campaign. It holds a special place to me. This is why i did it.
