Asteroids 2023

[gironde]

In the same spirit as 2022 NEO, here is the first asteroid edition 2023 (all Orbital class)

Attached is the file of the first 494 asteroids made official in 2023.
The parameters are edited from the JPL database: Small-Body Database Query

When the diameter is not known, it was calculated by the formula obtained on the site http://www.physics.sfasu.edu/astro/asteroids/sizemagnitude.html
which uses the value H (Absmag) in diameter according to the albedo (here 0.15 by default).

The mesh and texture are those used by Celestia Origin.

In comment of the line of the name we find the Orbital Class of each one:
jpl Class Family
MBA Middle Main Belt
IMB InnerMainBelt
OMB OuterMainBelt
CEN Centaur Family
ATE AtenFamily
APO ApolloFamily
AMO AmorFamily
MCA MarsCrosser
AST noFamily

reminder :
the first 4 digits of the name represent the year of the discovery
the following 2 letters represent the fortnight of the discovery:
AA from January 01 to January 15
AB from January 16 to January 31
...
YC from December 16 to December 31
the following numbers are a sequence number in the same fortnight knowing that for example, 2023 AA1 is the second because the first is 2023 AA

Today I submit to you 13 asteroids 2023 that were released after my extraction.
They therefore complete my file from yesterday. (494+13=507 ast.)

In the archive, you will find the file of the 13 new asteroids, and the complete file of the 507 asteroids to date and put back in order

JPL is making slow progress on uploading the 2023 asdsteroids and in addition they are not uploaded in the order of their designation
This complicates updates.
On 03/01/2023, I offer you the deactivated files of the various JPL updates at the same time as the recovery of my first file.
In addition, in the 'file complete' folder, there is the new complete file incorporating the JPL updates. Like this you can choose to start from the original file
and to complete it yourself if you had made changes; or resume the complete new file as it is.

the previous file had 507 asteroids and the new one 548 asteroids

new asteroids unnumbered for the year 2023 at 2023-03-07

These files represent the asteroids added since 2023-03-01 (asteroids unnumbered year 2023 N=548.ss_c) :
+ new asteroids 2023 BZ10.ss_c
+ new asteroids 2023 BA11 to 2023 BH11.ss_c
+ new asteroids 2023 CM4 to 2023 CR4.ss_c
+ new asteroids 2023 DY to 2023 DZ.ss_c
+ new asteroids 2023 DB1 to 2023 DF1.ss_c
+ new asteroids 2023 DM1 to 2023 DZ1.ss_c
+ new asteroids 2023 DA2 to 2023 DP2.ss_c
+ new asteroids 2023 EA to 2023 EK.ss_c

The "asteroids unnumbered year 2023 N=603.ssc" file is the new full file.


6 asteroides have been removed from the file because the JPL found that they already existed under another name:
"2013 YW33:2023 AP2" "Sol" # MiddleMainBelt
"2008 EO71:2023 AY3" "Sol" # OuterMainBelt
"2006 BJ278:2023 AK4" "Sol" # MiddleMainBelt

"2010 HJ15:2023 BC1" "Sol" # MiddleMainBelt
"2008 CM184:2023 BY1" "Sol" # MarsCrosser
"2011 QV21:2023 BU3" "Sol" # InnerMainBelt

For these 6 asteroides, I created a special file to take them back
under their main name in case you don't have them yet.
"asteroids unnumbered year 2023 with an other primary designation N=6.ss_c


Notes : Files .ss_c are tools of work and allow you to adjust your files.
The final file "asteroids unnumbered year 2023 N=603.ssc" is up to date (expurged of all duplicates)

2023 BM15 will no longer be in the next file for 'year 2023' if you have a file for 'year 2010'
this is where it should be put under the name: "2010 CJ88:2023 BM15" "Sol"

The site (www.physics.sfasu.edu/astro/asteroids/sizemagnitude.html) that I had found to calculate the diameter of asteroids as a function of H (absolute magnitude) no longer works

You can use instead in JPL:
