Stellar Body Collisions

I have pulled together a list of bodies that can potentially have collisions. Most of these systems need to be rescanned so that we can get the meanAnomaly from the journal and this will allow us to calculate the date, time and duration of the collisions. I'll be periodically updating the list, and in the next day or so will be able to include these in the Canonn Plugin POI list so that you can see any that are nearby if you are using the plugin..

I have code which is able to use the data gathered from spansh and perform the calculations but it needs a bit of callibration as it can be a bit hit and miss.

So it would be handy if you visit any of these systems to use Elite Observatory and the Collisions plugin and report the timings in this thread so I can compare against my own results.

The list of bodies can be found here: https://canonn.fyi/collsions

Confirmed collisions are held on the Canonn Calendar with dates https://canonn-science.github.io/canonn-calendar/

I can confirm Drojia XK-D c26-0 has colliders, and probably another 6 or so on the list - but I've currently broken my version of Colliders while trying to fix some of the calculations in it

.

Give me a couple of days and I'll have some data for you.

Drojia XK-D c26-0 is fascinating for it's own reasons though. Body 3b - despite supposedly being the outer moon is actually closer to it's parent than 3a; it has a lower SMA. And the parent itself has 2 rings (A and B) - not that you'd notice as the first is just 4km wide, and the second is 5km.

There are a little over 80 systems with sufficient data to calculate the collisions. Perhaps we should compare notes on calculated values.

I think my alt has found a new purpose. Would it be possible to add a galactic region column so I could know if I'm in the area of an unconfirmed collider?

Good idea I can do. It will require a little work to get it put in.

It looks like a few of these there are some small differences between the orbital periods store on spansh, so there will be quite a few that are acually binary or trojans. I'll see if I can eliminate them from the dataset

I've added some Collision candidates to the Canonn EDMC Plugin so that you can be directed to nearby systems.

If you could run Elite Observatory with the collsion plugin and report any that it confirms on this thread that would be nice. Otherwise just scan the bodies with the FSS and my software will pick them up and try and calculate dates.

I had someone today check a system and I ran my simulation forwards 20 years and it came up with a 2038 date. So don't expect instant results

Synuefai ZL-O b51-0 2 a and 2 b
Synodic Period 220.583 days
Next Collision at 12-Jun-2023 14:44

Duration: 29h 9m

2 a is a landable Icy Body with a Thin Argon Atmosphere Major Water Geysers and Biology

Bacterium Verrata - Blue $233,300
Fonticulua Campestris - Amethyst $63,600
Fumerola Aquatis - Orange $339,100

2 b is a landable Icy Body with Major Water Geysers

Even in daylight the sky is quite dark and reddish so probably not the best atmospheric collision we will find but at the terminator you can get some blue sky when facing the sun

This looks like it should be a good one for the Calendar. Both Canonn and Elite Observatory are within an hour of each other so this will happen with a high degree of confidence.

I wonder how visible the Neutron Star will be for Hypiae Phyloi AQ-X e1-69 looks like it only occurs every few years. I suspect it will be very dark and invisible sadly

I remember that one now - That's the one I asked you to pop to back in March. It should have 2 near misses in Oct this year and Oct next year before finally colliding. That said, I'm far less confident predicting collisions and near misses at the moment. Stupid maths

In case others didn't see, I've uploaded an updated Colliders here

This is what I have for you so far

I still haven't nailed the exact cause of the discrepancies between actual and predicted collisions, so I'm continuing to investigate. Shrogaei DW-N e6-1683 in particular is invading my nightmares... I suppose you could be a bit more confident where both Estimated dates/times match.

LCU No Fool Like One · May 21, 2022

Your Shrogaei calculations are way closer than mine. Perhaps we should exchange code and see if that gives us any clues

I'm going to try a few more things first, and I need to tidy things up - but yes, it might help. Look how different the estimates for my last one are!

What's annoying is that to my mind, both the estimate calculations I'm trying are wrong in some way. When I plug in what I believe to be the correct maths... then all the results are wrong. I'm must be missing something fundamental... and so I will end up reading more on Kepler's Laws and pretending I understand

@Mooing what are you using to get a second estimate?

I'm struggling to get my python code working reliably. Its driving me crazy.
