Retrograde Motion
Description:
Retrograde motion refers to the apparent backward movement of a celestial object in relation to the other stars or planets in its orbit. This phenomenon occurs when a faster-moving object passes by a slower-moving one, making it temporarily appear as if it is moving backward.
Sample sentences:
- During certain times of the year, Mars exhibits retrograde motion, causing it to appear to move in the opposite direction across the night sky.
- Astronomers have studied retrograde motion extensively to understand the complex orbital dynamics of the planets.
- Mercury periodically undergoes retrograde motion, leading to delays and miscommunications according to astrological beliefs.
