space-32-exam-06. Explain (Physics only) Distinguish stars from planets by explaining that stars produce their own light by fusion whereas planets do not for neutron star remnant. Use mechanism focus words: cause force gravity fusion radiation expansion attraction orbiting mechanism.

space-32-exam-06: A strong answer says that (Physics only) Distinguish stars from planets by explaining that stars produce their own light by fusion whereas planets do not in Our Solar System. For neutron star remnant, name the relevant object, stage, motion or evidence and connect it to the learning objective. Star life cycles depend on mass: nebula and protostar stages lead to main sequence, then lower-mass and higher-mass stars follow different final pathways. Finish by separating the idea from a misconception such as planet versus star, moon versus satellite, orbit versus rotation, or galaxy versus universe.

This exam response follows a precise chain: identify the Space Physics context, explain the mechanism or evidence, and protect the concept boundary. The mechanism focus makes this item distinct while anchored to Our Solar System.
