High Res - Tallantelli Spaceplane
Added 2019-01-27 13:27:13 +0000 UTCA high resolution version of a Kaybor-Kendy manufactured orbiter and launch vehicle used by the birrin. Current version of the birrin system no longer has two big moons as I couldnt find a stable orbit: if you know of real science about how it could come to be let me know!

Ooo thanks! Will have a gander :)

2019-01-28 04:36:43 +0000 UTCNote that i did no math for the above suppositions... so if you have done the math and considered those hypotheses i made... feel free to call me on it. They would make sense. Also consider the part of the "how much unstable" is said system. Because even a Lagrange moon would be unstable but it can hold for several billion years... and even a single million years would be enough actually to at least consider that a very normal for the Birrin. Our civilization is 100.000 years old but we've been doing "proper science" for less than 200 years and have historical records of less than 7.000 years. So the system might very well be "technically doomed"... but It has become in this configuration (due to giant gas drifts or whatever) only in the last million of years or so and won't be "effectively doomed" for another million of years. π π Sooo yeah it might be "doomed" but it also might mean it might boost their need to find a different suitable "home planet" and thus boost their space exploration and terraforming techniques, who knows. One million years is a blink of an eye in the cosmic scale, but it's 10 times what we as humans have been living until now.

2019-01-27 14:01:11 +0000 UTCIt's actually "simple" if you want two moons of relatively big size to be in a stable orbit around a planet, you put the smaller one in the Lagrange point of the bigger one. Preferably a same orbit Lagrange point, so the configuration shown there cannot exist, they would always be the same distance apart. But they have a comparable size (if the nearest is as small as it is shown) where the equivalent of Lagrange points 3 and 4 could be used. Lagrange 5 is too unstable for a smaller moon of that size It would be suitable only for an asteroid, really. Lagrange 1 and 2 are really only useful for microscopic satellites the size of artificial-made ones. If you want a pair of moons which are optically that size then the farther moon should not be a moon and should be farther apart, it would need to be essentially a binary planet system where the small moon orbits one of the two planets, and given the size of the smaller moon... it should be the POV planet in this picture, otherwise it would interphere too much with the two planets. The twin planet hypothesis orbit is... somewhat unstable. But only in cosmic scales, it can be held for a couple of billion years no problem, and could be caused by a major drift of a giant planet making two smaller planets "too close" which is actually "very common" as far as planetary events are. However for the farther moon to be that size... it should be the bigger of the two rocky planets in the twin planet orbit and also should definitively have an atmosphere. Unless we count a "mars hypothesis" where the father rocky planet has no magnetosphere and thus was stripped of almost all of its atmosphere. Also the fact that it's much closer to the sun would have sped up the loss of atmosphere, but since it had to be definitively bigger than mars to begin with... i doubt it would appear that rocky and defined, it would definitively need to be fuzzy and with a visible layer of thin atmosphere.
