3122 Florence update

I've updated Florence. I have used the orbital data from Wikipedia, they are more recent and more accurate, referring to September 1, when Florence had the closest approach to the Earth.

I would have liked to use the new ephemeris system, but I do not know how. And I do not know whether it is possible at all.

If you use the 'Asteroids-bin.sc' of Mosfet, you only need thie file:
3122FlorenceUpdPatch.sc
(1.02 KiB) Downloaded 716 times
(Put the file in 'addons\catalogs\planets')

Otherwise use this file:
3122FlorenceUpd.sc
(1.61 KiB) Downloaded 800 times
(Put the file in 'addons\catalogs\planets')
(If you have the old '3122_Florence.sc' file, remove it.)

With the new version, Florence is approaching the earth to about 7000000 km.

The object has been added in the script in OP, as well as JackDole's corrections regarding (3122) Florence.

I have added this object 2006 VW139 in my comets update I did a while back, I think you should add remove tag for the Sun orbiting object. so it would not get duplicated. I did add it like this Remove "2006 VW139" {ParentBody "Sol"}

I had originally added following data on 2006 VW139 the comets file. It had the minor planet designation added after 288P. I did also add it similarly on another main belt comet called 2003 BM80 adding it to SE as:

Comet "2003 BM80/(323137) 2003 BM80/282P 2003 BM80" Should I remove the 2003 BM80 after the comet designation of this object (282P) or should you add it after the comet designation (288P) of 2006 VW139?

Also I did discover that minor planets 2001 SN263 and 2003 AZ84 (I think the other one was this object) were missing their discovery dates, so I did at these on their data. I

Thank you for pointing this out. By removing 2006 VW139 the two components are missing the barycenter name, though.
Simply changing the name with 288P 2006 VW139 does solve the issue.
By judging from Wikipedia sources, the name should be separated (288P / 2006 VW139), but I don't see the urge to change both scripts for the moment, when they will be merged with default catalogs it will be dealt with. So I changed Asteroids-bin.sc to reflect your designation.
The important thing in my opinion is that the objects are reachable in search tool by entering "288p" or "282p", "2006 VW139" or "(300163)" and so on.
Missing dates added to the .sc file, updated in OP.

I am happy to help. However I just realized that TNO that was known as 1999 TC36 is now named after a creature from my country's ancient culture. It is now known as (47171) Lempo.

Thanks again! Name of asteroids updated in OP.

2017 YE5 is a near-earth binary which has been observed via radar, announced in July this year.
Apparently both components are very similar in mass and radius, so like they say, "it's twins!"

Several new binary asteroids were added to http://www.johnstonsarchive.net and I converted those data of objects from Kuiper and main belts, among others, placing them in asteroids-bin.sc file attached in OP.

These are the asteroids I added in no particular order:
Lummelunda, Susanvictoria, Tvashtri, Holt, Yuliya, Dietz, 2014 LQ28, 2005 SF278, 2015 QL14, 2008 CT190, 1997 GM40, 2013 FY27.

As some of you may notice I removed the tables, using spoilers instead. I really don't like the look of it, but it's faster and I decided to cut the frills: because of the important number of objects, that was taking more time that I'm willing to spend. That's also why I didn't add the scripts here to check as per usual. Please feel free to check the additions in the script.
For the occasion, I'd really like to thank again people who contributed to this Community Addon, here and in the old forum.

I would have liked to use the new ephemeris system, but I do not know how. And I do not know whether it is possible at all.
Didn't you use SE 0.980E patch?

I use SE 0.980_e.
But I meant for the asteroid '3122 Florence (1981 ET3)'. That's probably not in the ephemeris database at all.
And if it should be in, I do not know its parameters. (AnalyticModel, RotationModel)
