What is a planet’s obliquity?
Quick Answer
A planet’s obliquity is its axial tilt relative to the plane of its orbit. It helps determine seasons and how sunlight is distributed over the planet.
The Full Story
Obliquity is the angle between a planet’s rotational axis and the perpendicular to its orbital plane. Earth’s obliquity is about 23.4 degrees, which gives us seasons. Mars’s tilt is similar enough to Earth’s that it also has seasons, while Uranus’s extreme tilt of about 98 degrees produces very unusual seasonal patterns. Changes in obliquity over long timescales can strongly influence climate and ice distribution.
