egg changed the topic of #principia to: Logs: https://esper.irclog.whitequark.org/principia | <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly…

⟨Kerbinator⟩ ⟪sciencecompliance⟫ Then the rest of the planets have […] ⮪ Jupiter is also quite close to zero
<queqiao->
⟨sciencecompliance⟩ ⟪Kerbinator⟫ Jupiter is also quite close to zero ⮪ It's a few degrees off. Mercury is only a couple of arcminutes from zero obliquity.
<queqiao->
⟨sciencecompliance⟩ Anyone know if we are aware of any solar systems that have planets in retrograde orbits relative to others?
<queqiao->
⟨sciencecompliance⟩ Doesn't seem very probable to happen, but maybe there's a way it could.
<queqiao->
⟨Kerbinator⟩ ⟪sciencecompliance⟫ It's a few degrees off. Mercury is only […] ⮪ Jupiter is not tidally locked by the Sun. Don't know why, coincidence or doomed to be
<raptop>
Dunno about relative to eachother, ones where the planets are orbiting in a very different direction from the star's spin have been found
<queqiao->
⟨sciencecompliance⟩ ⟪Kerbinator⟫ Jupiter is not tidally locked by the […] ⮪ It's not, but my hypothesis is that Jupiter is close to zero obliquity because its spin just took a direction close to the direction of orbital angular momentum of the objects/particles that formed it.
<raptop>
The literature has planets that aren't coplanar, but figuring out the inclinations of non-transiting planets is sorta hard right now
<raptop>
Anyone got some spare LUVOIR or HabEx (preferably with the starshade) time?
<raptop>
...I wonder if Gaia data would help?
<queqiao->
⟨badgermasher⟩ That's always the ever present question, then you scratch your chin at the Gaia uncertainties and throw up your hands
<queqiao->
⟨sciencecompliance⟩ Iterestingly, Gaia is the feminine form of the Latin name Gaius.
<raptop>
Well, presumably I'd be throwing it in an MCMC thing with RV and/or transit data?
<queqiao->
⟨Kerbinator⟩ * it, "show it on navball" then it work
<queqiao->
⟨Kerbinator⟩ for MJ executing principia nodes
<queqiao->
⟨Kerbinator⟩ Edit: still be nice ~ tbh really good, the MJ executing principia node
<queqiao->
(however principia node will disappear from navball the instant burn finish, idk whether MJ has highly compensative method to do the last 0.00001m/s precision)

⟨Proxima-b⟩ It says "The parameters Maximal step count per segment and Tolerance control the accuracy of the computation of each segment (burn or coasting) of your plan. As explained above, a long flight plan with very accurate computations might make the game feel sluggish.", but didn't explain how
<queqiao->
⟨Proxima-b⟩ Does higher value cause lag or lower?
<queqiao->
⟨Soviet Onion⟩ higher means more computation
<queqiao->
⟨Soviet Onion⟩ especially if higher steps
<queqiao->
⟨leudaimon⟩ Higher tolerance and less steps make the computation faster
<queqiao->
⟨Soviet Onion⟩ ye, forgot to say tolerance lower also means more computation

⟨egg⟩ no it doesn’t.
<queqiao->
⟨egg⟩ The number of steps is the computation budget you allocate. The tolerance says how accurate you want that computation to be; with a fixed budget, the more accurate it needs to be, the smaller the duration that will be covered.
<queqiao->
⟨egg⟩ For the RP-1 veterans interested in trying out an extremely janky α of a contract system intented to get rid of the « get into this precise orbit » contracts which work so poorly with Principia, see #σκοπός.
