1. What is planetary rotation?Planetary rotation is when a planet spins around its own axis, like a top. This spinning motion creates the cycle of day and night on the planet.
2. How does a planet's spin make days and nights?When a planet rotates, one side turns toward the star and gets light, while the other side turns away and stays dark. This change between light and dark is what we call a day and a night.

Protoplanetary Disk: A rotating disk of dense gas and dust surrounding a newly formed star, from which planets form.
Diurnal Temperature Variation: The difference between the maximum and minimum temperature recorded over a 24-hour period.
Tidal Locking: A state where a celestial body's orbital period matches its rotational period, resulting in one side always facing the primary.
