    The American Heritage dictionary defines fire as: "a state, process, or instance of combustion in which fuel or other material is ignited and combined with oxygen, giving off light, heat, and flame."

    Because we define it as a reaction dependent on oxygen, fire can not exist without it. There are a few reactions, though, that produce heat and light in a similar manner to fire, but cannot scientifically be classified as fire because of the very definition of the word. One notable example is that of the nuclear reactions on the surface of the sun. These reactions, basically, convert hydrogen gas to helium, releasing lots of energy. This energy is sufficient to ionize all of the gases around the sun, resulting in a state of matter consisting of pure charged particles, known as "plasma". But because these reactions are independent of oxygen, we cannot technically refer to the sun as "fire"

    If a reaction similar to fire but with no oxygen was discovered on another planet, we would either have to redfine "fire" or find a new term for the reaction.

    The only other planet apart from Earth that appears to have oxygen is the planet Mars and the oxygen is trapped in the soil in the form of iron oxide. As the atmosphere on Mars is mostly carbon dioxyde fire could not happen.

    It would depend on the atmospheric composition of the particular planet. Oxygen is peculiar to just our planet, no other's that have been discovered have oxygen as the mian gas, but I doubt fire would burn on other planets like it does here on Earth.

    Does anyone here deny that there is fire on the sun? fire started there before oxygen was created.

    Fire is fire. Any fire, no matter where you are, needs 3 things:

    - an ignition (some to start the fire)

    - fuel

    - oxygen

    Without these 3 things, you won't have fire.

    if there isnt any oxygen a fire wont burn. it wont change just cuz ur on a different planet.

    well, there is no way to know that, since every other planet has different atmospheres. Also temperatures is a big factor,mainly because different materials have a different burn point than others. like I said, no way to tell.
