What Is the Brightest Planet in the Sky?

Venus is the brightest planet in the night sky. Venus reflects 70 percent of its light back into space. Sulfuric acid and crystals in Venus' atmosphere are good light reflectors. The moon, sun and the brightest star, Sirius, are the other brighter objects in the night sky.

Venus' temperature reaches over 460°C because it traps heat from the sun. This makes Venus not just the brightest but the hottest planet as well. For this reason, no living creature has been known to survive on the planet.

Italian astronomer Galileo Galilei first observed Venus with one of the early telescopes in 1610. Venus is named after the Roman goddess of love.
