Nuclear fusion
No, they are a source of light.
Stars are considered to be a light source because they are self illuminated. Stars are self illuminated because of the nuclear fusion occurring inside of them.
The main source of energy in the Sun and other stars is fusion of hydrogen atoms into helium atoms.
The energy source for stars, which produces vast amounts of heat and light, is the fusion of atomic nuclei in the star's core. In our own Sun, hydrogen is fused into helium; in older and heavier stars heavier elements may also undergo nuclear fusion.
The energy source of stars
The sun is closer to us than other stars.
No. They're too far away.
It have its own light
Light from the stars is energy. However, the amount of energy that this light accounts for is too small to be of any use.
on very very clear nights yes starts are almost the same size as the sun.
No, they are a source of light.
Nuclear Fusion at the Stars' Core.
Stars are considered to be a light source because they are self illuminated. Stars are self illuminated because of the nuclear fusion occurring inside of them.
The main source of energy in the Sun and other stars is fusion of hydrogen atoms into helium atoms.
A primary light source is one that actually produces light, such as a light bulb or the sun. A secondary light source in one that ONLY reflects the light produced by a primary light source. It doesn't produce light itself, such as a mirror or the moon.
The energy source for stars, which produces vast amounts of heat and light, is the fusion of atomic nuclei in the star's core. In our own Sun, hydrogen is fused into helium; in older and heavier stars heavier elements may also undergo nuclear fusion.
Stars are balls of gasses in plasma form. The high pressure and temperature in the core of the stars ignites a nuclear fusion reaction, that is the source of the light and energy emitted by them.
