The phenomenon Venus is brightest is when Venus orbits the distance from the Earth at the right distance. and is quite large in size therefore appears very bright in the sky for another period Even Venus has a thicker crescent. but with a position far from the world The brightness therefore decreased accordingly. Always seeing Venus in a crescent because Venus It is the second planet after Mercury orbits the Sun closer than Earth. Therefore, Venus cannot be seen fully lit up. Because it appears fully lit when behind the sun, so people on earth always see Venus appearing in a crescent. The thickness of the crescent varies at different orbital positions. And appear to be the most distant from the Sun, 47.8 degrees, so Venus can be observed in a short time before the sun rises or after the sun sets only. It never appears in the sky or at night.
