All stars do ... sort of by definition.
moon
No, the sun gives light to the moon, but not the stars. the stars give their own light.
A star is an object that radiates its own heat and light. A typical star is a superheated ball of hydrogen and helium that releases energy through nuclear fusion. The moon is much smaller and less massive than any star and is mostly made of rock. It does not produce its own light, but simply reflects light from the sun.
nebula
Because it is creating energy from the fusion of hydrogen and helium in its core.
Cities can be seen from space.
No, Venus is not a star. It is a planet in our solar system, the second closest planet to the Sun. Stars are massive celestial bodies that produce their own light through nuclear fusion, while planets do not produce their own light and instead reflect light from the Sun.
The earth does not produce its own light but it reflects the light rays from the sun that reaches its surface.
Luminous objects usually give out the light that they make on their own. An example of a luminous object is a star or an LED lamp.
The moon is not a star. The moon only reflects the suns light. Only stars make light. Our sun is a star.
A Star will produce its own light, through the nuclear fusion of hydrogen, which releases vast amounts of energy. Planets are not large enough for the required conditions to occur for this reaction, so they don't produce energy in this way.
All planets orbit around a star, such as the sun. They are spherical in shape due to their gravitational pull. Additionally, they do not produce their own light, but instead reflect the light from their star.
