what is the morning star?

The morning star typically refers to Venus when it's visible in the sky before sunrise. Venus is one of the brightest objects in the sky (after the Sun and Moon), so it stands out during dawn.
It’s called the morning star when it appears in the east before sunrise, and the evening star when it’s visible in the west after sunset.
The name has also been used symbolically in literature, mythology, and religion, often representing light, hope, or new beginnings.
