The DEATH STAR
Alpha Centauri, although it appears to the naked eye as a single star, is a binary pair. Together they are designated Alpha Centauri AB, the more massive and luminous in the pair designated Alpha Centauri A, the less massive and luminous Alpha Centauri B. Together, this pair is the third brightest "star" in the night sky. There is a third star probably interacting gravitationally with the pair, Proxima Centauri, also designated Alpha Centauri C, a red dwarf which is not visible to the naked eye but is the next closest star to our Sun. Alpha Centauri B has about 90% of the mass of our Sun and is about 45% as bright. Note that Alpha Centauri B is not the "second" star (second brightest) in the constellation Centaurus: that is Beta Centauri, which is itself a trinary star system.
A star is a luminous globe of hot gas that makes energy.
A planet is a non luminous object revolving a star in space.
Depends on how you define power. If we take it as transferring energy then it will have to be the most luminous. So the most luminous star known in the Universe is R136a1
Pollux
A star generates energy, including light, which it emits into space, i.e. it is luminous. A planet can only be seen because it reflects the Sun's light, i.e. it is non-luminous.
We have stars because the main star is the sun and there is other stars in space that are luminous globes of heat.
omg, I had the EXACT same question, but I suddenly figured it out: STAR!!
Generally, the more massive a star is, the more luminous they are. The most luminous stars appear blue.
because the star is luminous.
a star is made up of burning gases which makes it a luminous body. the sun is the only star in the solar system. the brightest star except the sun is sirius

Moon , stars , planets , anything we can see that emits light .
