Cusat Ite's Answer
Friction is the heat released when two or more masses make contact as they are moving past each other or in different directions.
The heat is simply energy converted from the kinetic energy the masses or objects have because they are moving. If they make contact, they will slow down, even if only slightly. As they slow, they must release energy, and some of that energy is released as heat.
There is no friction in space.
Space is a vacuum with a lot less particles than found in air so a lot less friction.
