Gaarst

They glow, but not much. For a blackbody (stars can be considered as such) the wavelength of strongest light emission on the spectrum is given by Wien's Law. This wavelength depends only on temperature. Also, the strength of this spectrum (power) is given by the Stefan-Boltzmann law and is proportional to the area of the star and its temperature to the power 4 ! The Sun, which has a surface temperature of 5800 K, has a peak wavelength of 500 nm. As they don't fuse, brown dwarves are a lot cooler, rarely hotter than 2600K and often several times smaller than our Sun. Assuming a really hot brown dwarf half the size of our Sun, this gives a peak wavelength of 1.1 µm and a total power that is 64 times weaker than that of our Sun. So not only the star would radiate much less than our Sun but it would also mostly radiate in the invisible infrared. Actually, the Hertzprung-Russel diagram indicates that, on average, brown dwarves are 100 to over 10000 times less luminous than our Sun.

Here.

Corrected my post accordingly.

I did free fall ... into Kerbol... ... from 681 million kilometers. 64 Kerbin years to reach apoapsis at 681,115,695,039 m, and another 64y to crash get to Kerbol.

First thing to take into account is that Minmus's density is 29.2 g/cm3, this is denser than any known element at standard pressure and temperature (Osmium the densest element is at 22.6 g/cm3). But suppose Minmus exists as it is in the Earth system, with the same mass and radius. About manned missions: 470 Mm is only slightly further than the Moon (380 Mm) and the surface gravity is several times smaller than the Moon's. So I think it would be easier to get to Minmus than to get to the Moon. We will probably have been there before going to the Moon, as even though insertion burn would be greater, the lander would need to be a lot smaller, and less powerful. Permanent human occupation, if it happened, would most likely take place on Minmus due to its weaker gravity, as it would be easier to take materials or humans to its surface. Its ice layer could also easily provide water for its inhabitants. The greater distance to Minmus would actually be a good thing for space travel: after going to the Moon, our only option for manned flights is Mars. With Minmus at this position, there actually would be an intermediate destination before Mars. It would be easier to test vessels or general interplanetary technologies. Assuming space conquest happened at the rythm it did in real life, I think we would probably have sent humans to Minmus, and we would be more advanced in our Martian programs, at least technologically and biologically. Also, due to this proximity of orbits between the Moon and Minmus, the latter's the great distance from Minmus to the Earth, Minmus' orbit would most likely be unstable. It would risk being ejected from Earth orbit anytime. Assuming Minmus would be made of extremely dense ice, then the most plausible scenario for its origin would be that Minmus was once two very large comet from the outer solar system. They somehow impacted each other and fused, making this extremely large comet (60km radius). Its orbit would have been modified and after several gravity assists by Jupiter or Saturn it would have ended up being captured by Earth. If you take a 10x radius for Minmus (600km), then it is trickier as bodies this size are essentially made of rock, and form by accretion (with the exception of the Moon). That would make Minmus somewhat between Enceladus and Ceres, though surface features would be very different. Minmus would then be made of rock covered by a thick ice layer. The large flat surfaces of Minmus could have been caused by an impact ejecting a part of Minmus' ice layer, and leaving the rocky interior exposed. A plausible scenario for its formation would be that it was originally formed as a moon of Jupiter or Saturn. For some reason, Minmus formed very closed to its parent planet or another moon. This unstable orbit would have thrown Minmus extremely close to its planet, tidal forcces ripping off a part of its ice layer, and was then ejected to a solar orbit. Then, it stayed on an unstable orbit, was disrupted by Jupiter and eventually captured by Earth. Another scenario for Minmus' formation would be similar to Ceres': a protoplanet that never got large enough to be a proper planet. Either formed in the Kuiper belt, or somewhere between Mars and Jupiter, it would have been captured by Earth like the scenari above. Assuming Minmus was indeed formed in the outer solar system (either orbiting a gas giant or in the Kuiper belt), studying it could provide precious information about this part of the solar system. In our system we need to send probes to comets or in orbit of the gas giants to get such information. It would be much easier to land probes or rovers on Minmus, and bring back samples, and huge amounts of data.

Yes you're right. When I looked at densities for having a comparison, I just took titanium because its density was close to Jool's, but I didn't pay attention to the significance of these numbers. Anyway, my point was to show that even though Jool has realistic density for a planet, that would be for a terrestrial planet, not a gas giant. I should have just said that Jool was 4 times as dense as Jupiter, that would have made more sense. Thank you for correcting me !

I'd prefer the add-ons section to be categorised. There was a thread about it some time ago, can't find it though.

I think you mean fusion, not fission. Anyway, it's not a question of size, but mass. According to the wiki, Kerbol is 1/3 of the Sun's radius but only 1/113 of its mass. As I said in my previous post, astronomers usually consider that 13 times the mass of Jupiter is the lower limit to be able to fuse deuterium. Above this mass, the body is considered to be a brown dwarf. To be able to sustain durable fusion reactions, it would have to weigh 0.07 solar masses (~75 Jovian masses, 8 Kerbol masses). It would then be classified as a red dwarf. Red dwarves as small as 1/5 of the Sun's radius are known to exist, so on a size perspective, Kerbol wouldn't probably change much. On the other hand, it would have to multiply its mass by 10, and that would greatly affect orbits. To sum up: Kerbol wouldn't crash into Kerbin, Kerbin would crash into Kerbol.

Did anyone manage to actually touch Kerbol's atmosphere since whatever release introduced it ? Without cheating of course Anyway, going to give it a try someday.

You know what a star is right ? If it doesn't fuse, it's not a star. The end.

Kerbol couldn't shine and Kerbin would have a density of 5 times that of lead (58 t/m3 against 11 t/m3). The Kerbol is just not massive enough for nuclear fusion to trigger, with a mass of approximately 10 Jupiters. The mass of 13 Jupiters is usually the threshold between gas giants and brown dwarves, under this mass the body can barely fuse deuterium (the easiest element to fuse). Actually the Kerbol would be surprisingly light compared to its radius (density of 230 kg/m3), 7 times less than that of the Sun. Even Jool, the least dense of all planets (by far) would have to be made of titanium to have such a mass. To sum up: All planets are made of super dense material, Jool is made of Titanium, and the Sun could be used to seal a large bottle of wine.

KSP doesn't use multithreading (for now) and is very CPU demanding. Laptops CPUs, even high end, tend to have slower frequency than desktop ones; so that may be the reason why you're having lag. The full specs of your PC would be helpful to determine if there's anything abnormal.

I agree, but meanwhile we're still waiting for infinite electric charge in the cheats menu...

1. Done 2. Done for a few atoms 3. Not done yet in a controlled way with normal matter. There is active research on it for clean nuclear energy 4. Never done outside a star AFAIK 5. Could be done 6. Tricky indeed, I don't really know if that's feasible 7. Pulse propulsion was considered for a time (Orion project, also exists in KSP) with nuclear bombs. So it could work. Somewhere in the future it might be feasible. I don't know if it will be worth the trouble though: who knows, we might have discovered FTL drive then...

There it is ! 8.9t at launch, two stages. First stage is liquid powered, has 900kN thrust and burns for 6.8s. TWR at launch: 9.60 asl. Second stage is solid powered, has 1080kN thrust and burns for 8.3s. TWR at activation: 28. According to KER, max TWR is 195 ! Top speed was ~3700 m/s, max G was 91.2g and apoapsis at 391 km. Max temp percentage was ~90%, but got as high as 95% on some flights. Didn't blew up anything during flight ! It uses parts from: Ven's Revamp (1st stage engine and structural bits), SpaceY (2nd stage boosters) and Procedural Fairings. I also used RSS and Real Fuels. EDIT: I am actually going to try hitting Mach 10 in 10 secs, 5 secs if I feel like it. EDIT2: Working on a version topping at 180g and Mach 20 after 16.5 secs of burn, reached >2000km apo. It leans to one side for some reason and often ends up flipping, trying to fix this.
