Wow, I'm actually quite surprised, but looking at this thread, I'm still holding the record for the largest star and largest procedural planet in Space Engine a year after setting them

time to play catch up, people!

from what I see, the largest star today is still RS 0-0-0-1016-18121-0-0-178 with a diameter of 167.02 AU. Here's a screenshot:

ok I'm still an idiot. Why can't we delete posts we accidentally submit while still working on them?

anyway, screenshot of record star: [img]http://forum.spaceengine.org/Wow,%20I'm%20actually%20quite%20surprised,%20but%20looking%20at%20this%20thread,%20I'm%20still%20holding%20the%20record%20for%20the%20largest%20star%20and%20largest%20procedural%20planet%20in%20Space%20Engine%20a%20year%20after%20setting%20them%20 time%20to%20play%20catch%20up,%20people!%20 from%20what%20I%20see,%20the%20largest%20star%20today%20is%20still%20RS%200-0-0-1016-18121-0-0-178%20with%20a%20diameter%20of%20167.02%20AU.%20Here's%20a%20screenshot:[/img]

and here's the largest procedural planet I've found (500 000 km in diameter. Rookies) (jk by the way, I love the fact that I'm not the only one looking for the biggest planet anymore): RS 0-0-0-521-4043-0-0-94 1 Image (might also be the planet with the lowest ESI ever at 0.012) it has a diameter of 743 094 km

note: I keep saying procedural because the largest planet period is HD 100546 b with a diameter of 986 589 km, but it's a catalogued planet and not a procedural one

oh and I almost forgot about this: RS 0-4-1828-387-2027-0-0-46 8 is a planet with 280 moons, although I believe it's actually not the record holder for the most moons, but I can't find the actual record online so I'm submitting it Image

alright, now let's beat some records!

this is seriously humiliating. Screenshot links, much simpler:

there. It took me 3 replies (which I seemingly cannot delete so this will stay embarassing forever) but there are the screenshots

Aside from the ridiculously enormous planet (which is clearly silly), how is that 9th planet at 1°C and the others around it are at hundreds of °C?!
(also yeah, until you post 10 times you will barely be able to do anything here. Just post pics on the image dump or something until you get there and then you'll get the full post functionality)

Oh my god I haven't even noticed that before! I'll look at it when I can, that's weird

here, I've taken a screenshot of that selena's stats https://sta.sh/01s4vlbvoxll

I'm still dumbfounded. The second planet in the system is very similar to it, outside of orbital period, semi-major axis and temperature. In fact, the only other differences I can see is the axial tilt. Here, take a look at it https://sta.sh/0q3f5yzbtbn

definitely strange

Has anyone found a hierarchical system with 7+ stars (that aren't the ones around supermassive black holes in the centre of galaxies)? They can be searched for using the filter but I've never seen one - or even one with just 7 stars. Are they even in the game?

θ Orionis has over a dozen. From 41 Orionis A to H, or HD 37020 to HD 37023,.
Spread out over various systems, it is really an open cluster. I don't think there are any known septenary hierarchical systems, and so none are generated procedurally by SE.

Just to be sure, what do you mean by hierarchical?

"hierarchical" is just like any smaller multiple system, with everything orbiting a single barycentre and the 'sub-systems' orbiting their own barycentres etc. a hierarchical 6-star system is usually three binary systems which could be all orbiting one barycentre or could be split off into two binaries that orbit their own barycentre, which in turn orbits the main barycentre (while the other binary orbits the main barycentre).

Like the Castor system. Each of the three 'stars' is a binary system in reality.

and septenary meas 7 right?

because if you use the search tool you can actually find a couple of them (and I mean procedural ones)

yeah I haven't found any 7 star systems using the filter yet, and nothing with more stars in them either - which is what I was asking about in the first place. Has anyone found a system with 8 or more stars (that wasn't a central galactic supermassive black hole and its companions)?

I looked through my saved locations and guess what?

https://sta.sh/02d54f70h0vs

RS 0-0-0-733-17113-7-2089718-166 is an octuple system with two planets. They do exist!

I think I'll make one comment because I seem to have three more hidden gems in those saved locations (in terms of records)

turns out I had found the darkest star ever https://sta.sh/0yrqk2lkkr8

RS 0-2-4-338-4073-8-11252715-449 AB is a Y9.9 V brown dwarf with a luminosity of about 4x10[sup]-15[/sup] on the brightest part and 0 at the darkest. Yes, this star (at least in some spots) emits no light whatsoever! https://sta.sh/05bxb8uy1ga 

before the luminosity reached zero, I managed to get a screenshot where the luminosity was at 3.7x10[sup]-30[/sup] https://sta.sh/01kd2guzhknm (at one point it reached 10[sup]-32[/sup], but at that point I was moving so slowly the orbit of the star affected my reading!)



https://sta.sh/01y1s5x4q0ns (RS 0-0-0-163-17115-6-243428-398 2.1) this planet might have the deepest ocean yet at 160 km in depth. Crazy thing is that the temperature at the bottom of the ocean reaches 1653.8°C!



https://sta.sh/014sccdyu4dh not sure if it's a record breaker, can't be bothered checking, but RS 0-0-0-1016-7606-0-0-520 5 is a warm terra with a semi-major axis of 974 AU and an orbital period of 1755 years. However, just to make this even crazier, its rotational period is about 10 hours and a half. If my calculations are correct, this means that this planet's year contains 1.46 million days!
