SOLAR SYSTEM

Detailed explanation-1: -A star is a huge glowing ball of hot gas. Deep inside its core, hydrogen atoms smash together, forming helium and releasing huge amounts of energy that heats the gas. This is called nuclear fusion, and it’s why a star shines. As the hot gas pushes outward, it opposes the inward pull of gravity.

Detailed explanation-2: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.

Detailed explanation-3: -The Sun is a main-sequence star, and thus releases its energy by nuclear fusion of hydrogen nuclei into helium.

Detailed explanation-4: -Overview: A star is a huge luminous ball of hot gas, mostly hydrogen and helium, held together by gravity. Nuclear reactions in the cores of all stars, including our Sun, produce energy in the form of light. Stars shine because this light works its way to the surface and radiates out into space.

Detailed explanation-5: -For most of their lives, stars fuse elemental hydrogen into helium in their cores. Two atoms of hydrogen are combined in a series of steps to create helium-4. These reactions account for 85% of the Sun’s energy.

Detailed explanation-6: -What makes stars shine? 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-7: -Stars are born in nebulas. Nebulas are clouds found in space. They are made of gases and dust.
