No.
Yes because if the sun didn't shine it won't be bright
It reflects light from the sun.
The sun shines bright because it undergoes nuclear fusion in its core, converting hydrogen into helium and releasing energy in the form of light and heat. This process is what provides the sun with its brightness and sustains life on Earth.
Venus, because it is close to the Sun (and very bright) it is seen either before the Sun at dawn or after the Sun at dusk.
The correct spelling for "shining" which means "to give out a bright light" is shining.
Since the sun (a star) is so bright, no other star can shine during the daytime.
Adjectives that describe the sun shine are words like "bright," "warm," and "happy." Although, some could describe them as "treacherous," "burning," or "dangerous."
Venus shines brightly because it has a highly reflective atmosphere made up mostly of carbon dioxide, which reflects sunlight extremely well. This, combined with its proximity to Earth and its thick cloud cover, makes it one of the brightest objects in the sky after the Sun and the Moon.
The Sun is significantly brighter than Venus. Venus appears bright in the night sky due to its proximity to Earth and its reflective atmosphere, but the Sun is the brightest object in our solar system by far.
Venus
In fact, both planets are dark. The only reason Venus looks bright to us is not because it has it's own light, but because it reflects light from the Sun. It's the same thing for Mercury.So, both Mercury and Venus appear bright to us.
Venus is sometimes called "the evening star", although it is a planet. This because it is very bright and always appears close to the Sun in the sky. So, sometimes it appears in the evening as the Sun sets, looking like a very bright star.
