the THIRD helium white rhino discovered

[Arcane26]

Are you kidding me? We don't discover one for like half a decade and all of a sudden we get 2 in the same month!? Well, yes.
May I present to you, in the the Newton's Vault region, discovered by Kurgubigelzi, Swuemuia EJ-L c10-0 4:

She is 15.3 Earth Masses and has four landable moons. Orbiting 2.1k ls out around a K type star, she is still well lit. But look at this:

Where is the helium? It's basically equally split between ammonia, methane and nitrogen... this composition is more reminiscent of the original helium white rhino with 99% nitrogen... but it still had helium. This has none. Here are more pictures. And I want to know your thoughts on our 2 recent additions to the HGG list.

It's something I've seen very, very often in the Stellar Forge: a precise 1:1:1 atmospheric mixture of methane, ammonia and nitrogen. Always on planets and moons rather than in gas giants themselves, of course, but it still seems to be an odd quirk of the Forge to always want to generate that precise ratio, which I don't believe has a real-world logical explanation in terms of planetary chemistry. The only real-universe world we know with a similar atmosphere - Titan - has a ratio of 0:5:94 (ammonia is zero because Titan is too cold; on Titan, ammonia is, like water, effectively a type of rock).

We can only assume that buried within that 0.4% of composition that is unaccounted for (33.2% x 3 = 99.6%), hydrogen and helium are both being measured (though unreported as both being below 0.1%) and the helium measures higher, thus earning the planet the HGG label.

Fascinating. Now that you mention it, I believe I remember seeing that exact same atmospheric mixture on many planets. And I suppose there isn't a way to see the values below 0.1%?

I don't know if that stuff ends up getting into the journal files; you'd have to check with the journalling gurus. It doesn't end up in the EDSM stats page for planets, so I suspect the answer is "no". Just one of many things the game goes to all the trouble of calculating, only to throw it away again by not journalling it.

EDSM does show a more precise percentage level, though: "33.21%", giving us a total of 99.63%, and a missing remainder of 0.37%.

I'm happy that procedural ones exist, makes search for one feel less futile excercise.
Looks like classification "Helium Giant" is for any Gas Giant that has more Helium than Hydrogen in the atmosphere, even if the game doesn't show the elements.

Next on my bucket list: find Raxxxla.
