Question

What angle does it make with the plane of the orbit?

Answer 1

The earth’s axis is tilted at an angle of 23°30′ from the line perpendicular to the plane of its orbit. Consequently, the axis makes an angle of 66°30′ with the plane of the orbit passing through the center of the earth. This tilt is responsible for the variation in seasons and the differing lengths of day and night throughout the year.
