The brightest planet in the solar system is Venus. It shines brightly in the sky due to its thick atmosphere, which reflects sunlight very effectively. Venus often appears as the third-brightest object in the sky after the Sun and the Moon, earning it nicknames like the “Evening Star” or “Morning Star.”

Venus is the brightest planet in the solar system. It stands out in the night sky because of its thick, reflective atmosphere composed primarily of carbon dioxide and clouds of sulfuric acid. This atmosphere reflects sunlight very efficiently, making Venus shine brightly. It is often visible shortly after sunset or before sunrise, earning it the names “Evening Star” or “Morning Star.” Venus’s high albedo, or reflectivity, contributes to its intense brightness. Despite being farther from Earth than some other planets, its exceptional reflectivity allows it to be the third-brightest object in the sky, after the Sun and the Moon.
