Jupiter is a bright planet, and Mars is sometimes bright, too. But neither Jupiter nor Mars at their brightest can outshine Venus. Why is Venus so bright? Our neighboring world – orbiting one step inward from Earth around the sun – is the 3rd-brightest natural object in the sky, after the sun and the moon. It’s currently a brilliant light in the mo...
As the planet next inward from Earth in orbit around the sun, Venus is relatively nearby. But its nearness isn’t the only reason Venus is bright. Consider that Mars orbits one step outward from Earth. And Mars waxes and wanes in brightness in our sky over about a two-year cycle. It’s only exceptionallybright around the time Earth passes between Mar...
The albedo of Venus is close to 0.7, meaning it reflects about 70% of the sunlight striking it. When the moon is close to full in Earth’s sky, it can look a lot brighter than Venus. But the moon – whose surface is dark volcanic rock – reflects only about 10% of the light that hits it. The moon appears bright to us because it’s close to Earth. It’s ...
Venus is brightest when two factors combine – the phase of its crescent, plus largest overall size of Venus’ disk – so that the greatest amount of surface area of Venus shows in our sky. Astronomers call this greatest illuminated extent. Why does it happen? Because Venus orbits the sun inside Earth’s orbit, it sometimes goes between us and the sun....

All planets shine by reflecting starlight from the star they orbit, which in the case of Venus is the Sun. The brightness of a planet is determined by a combination of three different factors. Factor one is the planet’s distance from the Sun.

1. Composition of Venus’ Atmosphere. The thick cloud cover that enshrouds Venus is one of the key factors behind its dazzling brightness in the night sky. Unlike Earth, where clouds are primarily made up of water vapor, Venus has a dense atmospheric layer formed by sulfuric acid droplets. These clouds have remarkably efficient scattering ...
