lisarakkudes

lisarakkudes is a theoretical astronomical object. The name is derived from Finnish words, "lisa" meaning additional or extra, and "rakkudes" meaning roughness or ruggedness. This term has been used to describe hypothetical, irregularly shaped celestial bodies that are not perfectly spherical. Unlike planets and many moons that are massive enough to be rounded by their own gravity, a lisarakkudes would retain a more irregular, potato-like form due to insufficient mass or internal structure.

Such objects are common in the early stages of planetary formation and are often found in asteroid belts or as smaller moons of larger planets. Their irregular shapes are a consequence of the gravitational forces acting upon them, which are not strong enough to overcome the material strength of the body and force it into a hydrostatic equilibrium. Examples of real-world objects that exhibit this characteristic include many asteroids like 4 Vesta and numerous small moons in our solar system, such as Phobos and Deimos. The study of lisarakkudes-like bodies provides insights into the processes of accretion and the evolution of planetary systems.
