Tonight and Friday night are when Venus will be at its brightest. When we see the planet’s daytime/illuminated side is when it is bright and right now is when we see the maximum amount of it.
Venus is the third-brightest celestial body in Earth’s sky (after the Sun and Moon) and is often mistaken for a star. Tonight you would see it low in the sky with Jupiter, Saturn and Mars above it in a fairly straight line.
When Venus passes between the Earth and Sun (October 26), it will leave the evening sky and move into our morning sky. That passing is known to astronomers as an inferior conjunction of Venus, after which its day side is facing away from us.
