Nuclear fusion.
A star is a body of gas that gives off tremendous amounts of radiant energy in the form of light and heat through nuclear fusion reactions in its core.
Gravity pulls the star in and tries to squeeze it down to a point. Because it pulls all of the atoms of the star in to the middle, gravity speeds them up, giving them energy. Eventually gravity gives enough energy to the atoms that they move fast enough that when they collide, they sometimes stick together and nuclear fusion happens. This is what gives a star its light and what keeps a star from collapsing further.
well our sun is in our galaxy and our sun also give out light and energy but i did not say the sun is a galaxy is just our star that we circle around and gives us day and night and gives us heat, you know?
That's called a star. Actually stars are balls of plasma - where plasma can be thought of as a special case of a gas.
It is a ball of gas, yes. Energy I'm not sure. Maybe womone else can give that answer.
Nuclear fusion does.
The form of measurement that can be defined as the rate at which a star gives off energy is luminosity. Luminosity is measured in watts and indicates the total amount of energy emitted by a star per unit time.
No. Sol is a mediocre star. Not too bright, not too dim. It gives off more energy than some, and less energy than some.
Quasar.
Yes, unless you call a dead star, that gives off no light at all, a "star". Each star has its lifetime - it will eventually stop producing energy. Also, the material out of which stars are made will eventually be used up.Yes, unless you call a dead star, that gives off no light at all, a "star".

A star gives off light through a process called nuclear fusion, where hydrogen atoms in its core combine to form helium, releasing energy in the form of light and heat.
The sun is a star because it gives off energy through nuclear fusion in its core. It is the closest star to Earth and is the center of our solar system, around which the planets, including Earth, orbit.
No because they got red bull and it gives you wings XD
Answer: A shooting star Answer: One with a small surface, such as a white dwarf or a neutron star. These are "dead stars", in the sense that energy production has stopped.
