Detailed explanation-1: -Though sun is not the biggest or brightest star, it appears so because it is the nearest star from us. Since the distance is very less, it appears bigger and brighter.
Detailed explanation-2: -2) The Star’s Distance from Us However, just because a star looks brighter, doesn’t mean it actually is brighter. A star’s brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears.
Detailed explanation-3: -This is because the stars are at all different distances, so the nearby ones appear bright even though they may be intrinsically not so bright.
Detailed explanation-4: -In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
