The term "planetary axes" refers to the imaginary lines that run through a planet from its north pole to its south pole. Each planet in our solar system, including Earth, Mars, and Jupiter, has its own axis, which is tilted at a specific angle. This tilt affects the planet's seasons and climate, as it determines how sunlight is distributed across the surface. The angle of a planet's axis can vary significantly. For example, Earth has an axial tilt of about 23.5 degrees, leading to distinct seasons. In contrast, Uranus has an extreme tilt of about 98 degrees, causing it to rotate almost on its side. Understanding planetary axes helps scientists study planetary behavior and climate patterns.
