The planet known as the "Morning Star" is Venus. This nickname arises from its bright appearance in the sky, especially just before sunrise. Venus shines due to the reflection of sunlight off its thick cloud cover, which is composed mostly of sulfuric acid. It can often be seen in the eastern sky during dawn or in the western sky after sunset, making it one of the most luminous objects in the night sky. This designation is part of its historical significance in various cultures, where it was often associated with deities related to beauty and love.
