WebMar 14, 2024 · Earth's rotation period is about 24 hours, or one day. Axial Tilt Some planets, such as Mercury, Venus, and Jupiter, have axes that are almost completely perpendicular, or straight up-and-down. Earth's axis is not perpendicular. It has an axial tilt, or obliquity. Axial tilt is the angle between the planet's rotational axis and its orbital axis.
