Detailed explanation-1: -This fusion process creates large amounts of heat and light. When a mass of hydrogen begins the fusion process, it is classified as a-star.

Detailed explanation-2: -When a mass of hydrogen has enough density, it begins to fuse the hydrogen atoms together. This produces heat and light.

Detailed explanation-3: -Stars produce their energy through nuclear fusion. For most stars, this process is dominated by a process called the “proton-proton chain, ” a sequence of events that transforms four hydrogen atoms into one helium atom.

Detailed explanation-4: -Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

Detailed explanation-5: -A main sequence star is any star that has a hot, dense core which fuses hydrogen into helium to produce energy. Most stars in the galaxy are main sequence stars, including Alpha Centauri A, Tau Ceti and the Sun. Stars are formed by the gravitational collapse of gas and dust from the interstellar medium.
