The substances which have very low ignition temperature are called inflammable substances. These substances catch fire very easily. LPG, petrol, and alcohol are some examples of inflammable substances.

Substances that can burn or undergo combustion are called combustible substances. Paper, clothes, wood, LPG are all combustible substances.

there is a lot of difference between a star and a planet. A planet may be a result of collision of star, but star is not a result of collision, instead, a star is formed mostly by combination of gases(helium most probably). A planet is smaller in size as compared to a star. but stars are of larger sizes, larger than the size of our sun.
