Of course, youll want to do this all to scale in relation to the % increase in the stars mass. For example, if in KSP this planet youre trying to make was 0.5 AU away from a 50 solar mass star, but in US2 its a 78 solar mass star, youll need to move that planet farther than 0.5 AU and make it larger as well. That means youll have to scale up the size of the planets as well as their distances from the star in order to compensate for the increase in the stars size, does that make sense?. So, the reason I asked if you were trying to make an accurate model of Kerbols system is because in this simulator the minimum mass a star can have is 78.6 solar masses, but I believe the star in the Kerbol solar system doesnt have that much mass. "close" in space is actually pretty damn far lol :P Another thing to keep in mind is that when I say "close" to a star, that is a relative term. I dont think that should happen unless the planet is extremely close to a star, but it is just a simulator on Steam so we cant expect its accuracy to be perfect and I guess thats what it boils down to. It is weird that the silicate and iron is evaporating too though. This is exactly why comets that orbit anywhere close to the Sun eventually disappear completely in real life.your planet isnt much larger than some asteroids/comets out there hehe. If any vapor happens to stay nearby, it will just be stripped away by the constant, relentless, unforgiving solar wind one particle at a time. Since your planet has such a weak gravitational pull, this vapor can easily drift off into space. When it does, ANY water or ice on it could be turned into vapor. So your tiny little planet can overheat extremely easily. On Earth, the Suns light has to pass through the atmosphere which absorbs/distributes/radiates/disperses a lot of the heat from the Sun But on the Moon where there is no atmosphere to travel through, like on your planet, when the Suns light touches the surface the temperature shoots to 300 degrees Fahrenheit because there is nothing to disperse the heat! Your planet simply isnt capable of retaining an atmosphere because of its feeble gravitational pull. This is what happened/ is happening to Mars' water and atmosphere (water vapor makes up a large part of the atmosphere). These highly energized particles, and the radiation that often accompanies them, travel at speeds that are difficult to fathom, from 560,000 to 1.7 million miles per hour!! When these particles collide with the particles that comprise a planets atmosphere they literally drive them away from the planet, stripping the planet of its atmosphere one particle at a time. Solar wind is just a term for the charged particles that are emitted from stars. If your planet does not have a molten iron core, it doesnt have a magnetic field to protect it from the solar wind like Earth does. Needless to say, your planet lacks the mass, therefore the gravitational pull, required in order to create a molten iron core. Ill do my best to explain but I am by no means an expert. I could be totally wrong, but Ill give it my best guess. This is the first major clue as to why your planet is evaporating, but of course it depends on all the variables I asked for above as well. Unless for some absurd reason your "planet" has an abnormally high density, I will assume that it has less mass than the Moon since its much smaller. You mentioned your planet has a radius of less than 1000km and in case you werent aware, that is smaller than our own Moon which has a radius of 1700km Needless to say, that means you have a TINY "planet". Evaporating isnt a bug or anything, its based on real physics (comets disappearing after getting too close to the Sun). Hey there ! > Basically, your planet is too small, and most likely too close to the star.
