The cheat menu objects can be more dense than the sun, or less dense than earths atmosphere

These objects can be 1000kg/0.01m^3 so 100000kg/m^3. The sun is 1400 kg/m^3. The only thing in the universe that beats these objects is a neutron star, and a black hole really. So, these objects will immediately start nuclear fusion and milliseconds later run out of stuff to fuse and supernova.

This isn't really how fusion works BTW.

Unless it is made out of hydrogen, confined within itself and heated to a few hundred million degrees, it'll just come apart really quickly, but won't fuse anything. 100,000kg/m^3 is less than the density of the Sun's core, and about twice that of the densest material known (under standard Atm conditions), so nothing too extreme.

Supernovae don't work that way either. You haven't got enough stuff out there to trigger an actual supernova mechanism. A hundred tons isn't that much.

Sorry I was kinda in

Sorry for rushed post without much research in it, but I was landing on duna, and my escape key broke(I am not kidding you, I am dead serious) so first, I meant that it will fuse if they are made of a lighter material like lithium or the such. Then, in a matter of a little bit of time, it should run out of mass, and either collapse and become a black hole, which there is not enough mass for, or it will lose its pull and explode.

Sure KSP isn't close to real objects about density, and quite impossible to do while keeping true gravity values (1 g on Kerbin at ASL) and gravitational constant (6.67408E-11).

Earth's density = 5510 kg/m^3, Kerbin's = 58484. Eve's density beats everything at 85197; Jool's density is lowest of planets at 4679 (quite impossible for a gas planet). If I'm correct plutonium is the densest natural element at 19816. While Squad tried to avoid bending physical laws (e.g. same gravitational constant), the reduced scale in kerbol universe brings to values impossible in nature.

100 ton / m^3 is 4/5 time denser than osmium, degenerated matter  in white dwarf stars is far denser. keep to 19 ton / m^3 for uranium or tungsten
