Axial tilt, or obliquity, affects the length of day and night by influencing the distribution of sunlight across the Earth's surface throughout the year. When one hemisphere is tilted toward the Sun, it experiences longer days and shorter nights, while the opposite hemisphere has shorter days and longer nights. This variation leads to the changing seasons, with more extreme differences in day length occurring at higher latitudes compared to the equator. Consequently, during solstices, some locations may experience continuous daylight or darkness for extended periods.
The axial tilt of a planet significantly influences its seasons by determining the angle and intensity of sunlight received at different latitudes throughout its orbit. For example, Earth’s axial tilt of approximately 23.5 degrees causes variations in solar radiation, leading to distinct seasonal changes as different parts of the planet receive varying amounts of sunlight over the course of the year. In contrast, a planet with little to no axial tilt experiences minimal seasonal variation, maintaining relatively consistent climate conditions year-round. Thus, the degree of axial tilt is crucial in shaping a planet's seasonal patterns.
Earth's axial tilt, also known as obliquity, is approximately 23.5 degrees. This tilt is responsible for the changing seasons as the planet orbits the Sun. The axial tilt can vary slightly over long periods due to gravitational interactions with other celestial bodies.
The Earth's rotational axial tilt causes the seasons.
The variation in the length of day and night increases towards the poles due to the tilt of the Earth's axis and its spherical shape. Near the equator, day and night durations remain relatively consistent throughout the year. However, as one moves toward the poles, the angle of sunlight changes dramatically, leading to extreme variations—such as continuous daylight in summer and prolonged darkness in winter. This phenomenon is a direct result of the Earth's axial tilt and its orbit around the Sun.
Nutation is a small, periodic oscillation in the Earth's axial tilt, occurring over an 18.6-year cycle. While it slightly alters the angle of the Earth's axis, its effect on seasons is minimal compared to the more significant axial tilt and orbit around the Sun. Nutation can cause minor variations in the timing and intensity of seasons, but these changes are generally negligible and overshadowed by the more stable seasonal patterns driven by the Earth's axial tilt and orbital eccentricity.

The axial tilt of Jupiter is 3.12 degrees.
It affects seasons by the angle a planet is tilted.
The sun ray hits only one area
The sun ray hits only one area
because it rotates in different parts which changes the temperature
Mercury. It seems to have an axial tilt of less than one degree.
because it has an axial tilt
Callisto does not have a tilt. It's axial tilt is zero.
It is 6.687°
Uranus's tilt of Axial is unusual because Uranus is tilted on it's side
