Earth's nearness to Venus is a matter of perspective. The planet is nearly as big around as Earth. Its diameter at its equator is about 7,521 miles (12,104 kilometers), versus 7,926 miles (12,756 kilometers) for Earth. From Earth, Venus is the brightest object in the night sky after our own Moon.

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....
Bottom line: You can’t miss dazzling Venus in the east before sunup now. It’s the 3rd brightest object in the sky, after the sun and moon. But why is Venus so bright? Read more: Venus before sunrise: Greatest elongation October 23, 2023
Jan 8, 2017 · A transit of Venus. Venus is the dark dot crossing the Sun’s surface – image from Wikimedia Commons. After inferior conjunction, it will appear to move away from the Sun and will rise and set earlier in the day and will start to become visible in the eastern sky before sunrise. At this point in its orbit Venus is known as the Morning Star.
Mar 24, 2014 · The planet also reaches two points in its orbit when the Sun-Earth-Venus angle lets us see it at its brightest. These events, known as greatest brilliancy, occur when Venus lies at an elongation ...
Venus, in contrast, varies its distance from us immensely. We can't see Venus when it's "full", because it's on the other side of the sun from us and lost in the sun's glow. It'll next be there a year from now, in April of 2013. But if we could see it when it's full, Venus would be a distant 1.7 AU from us.
