👉 In physics, a scission is an event in which two or more particles move apart due to the interaction of their forces. It is often used in the context of stellar evolution and planetary formation. A scission can be defined as a point where two or more objects, usually gas or dust, separate from each other due to gravitational forces. The distance between these objects changes as they move apart, creating a new structure within the galaxy. Scissions are an important part of star formation and are responsible
