The morning star that appears in the sky before sunrise is Venus. Venus is the second planet from the Sun and is often referred to as the "morning star" or "evening star" due to its bright visibility during dawn or dusk. Its thick atmosphere reflects sunlight effectively, making it one of the brightest objects in the sky after the Sun and the Moon. Observing Venus in the early morning or late evening can provide stunning celestial displays. Its periodic appearances contribute to its significance in astronomy and various cultural mythologies.
