Sorry for interfering, Patau, but I like things to be precise and I think that records shouldn't be included unless they are proven by pictures. Currently it's not the case, as some posters haven't done this properly, eg.
here rukmerot hasn't showed us all the bodies in the system (rukmerot, please, present pictures as spoilers in the future) so we can't verify his claims unless we go there and, actually, not only is the name of the system wrong (it's the name of a planet and it's wrong in your first post, too) but the number of planets seen on the pictures are different than he's claiming (I've counted 60 including the one that is blurred, not 61 - i.e. his 67 minus 6 belt clusters) so could be the number of all bodies. Everybody can make mistakes and this is why we should have an easier way to verify than to explore a system ourselves (I'll try to explore it anyway, but it is going to take time).
There is a similar issue with John Xenir's claim: his picture doesn't show the name of the planet but the name of its ring, instead, and this is why the name in the record is wrong (it shouldn't have A at the end). Moreover, I see on the picture 3,799.8276, not 3,799.8275 as he claims - perhaps it's a very small error but people, please, double check when posting because even such small errors can sometimes matter.
Rhysling, I'm waiting for your picture - there are many ways to present pictures without having forum rights (eg. an external link). I would love to see such a nice record proven but I'm too far away, currently, to verify it.
To be more positive: rep for CMDR Gerakis (largest body with ammonia-based life), SuperJogi (HD 217086), Minudra (smallest body with ammonia-based life) and Morkel (13 moons).
Back to exploring (BTW, my adventure with Lakon T-9 has surpassed my wildest dreams

- you wouldn't believe it, Patau, unless you'd see it again), I've forgotten to mention it earlier but, surprisingly, there is an unclaimed record in a system that almost 6000 commanders visit per 24h: Thinnest ring (in a multiring) - Leesti 1 A Ring at only 538km
Furthest distance between two Federation systems: 17 Draconis to Exphiay at 718.2 Ly
Furthest distance between two Imperial systems and Furthest distance between any two inhabited systems (I'd like to remind that these two I claim in the name of martianmar): Quince to Fehu at 914.35 Ly
I've had a lightest neutron star, as well, but it's already been beaten by SuperJogi by less than 0.08 solar masses
Have you seen it? They've vastly changed Jackson's Lighthouse !!! Nothing about the magnetar, the catastrophic collision of 2 white stars and the destruction of the Federal system some hundreds years back... and the system is consisting of less bodies, too! Is it because the collision would have unleashed so much energy that many systems should be affected? That's sad - it had been such a great story to imagine...
