What Is the Angle of Inclination of the Earth?
The angle of inclination of the Earth relative to the plane of the Earth’s solar orbit is 23.5 degrees. This angle of inclination, also referred to as the “tilt” or “deviation,” directly influences seasonal variations on the planet.
Earth revolves around the sun in an elliptical orbit, which takes approximately 365 days to complete. The plane by which Earth circles around the sun is called the “plane of the ecliptic.” The angle between Earth’s equatorial plane and the plane of the ecliptic is called the angle of inclination, which is the same as the axial tilt of the planet.
The different seasons are due to the rotational tilt of Earth’s axis. Places that are tilted towards the sun experiences the summer season, while those that are tilted away from the sun experiences the winter season.
