What is the earth's axis when it revolves around the sun?

Answer 1

Pretty much fixed (pointing at the north star),

so it's tilted from the perpendicular to its orbit by about 23 degrees.

(Thus the seasons.)

Answer 2

The Earth's axis remains tilted at approximately 23.5 degrees relative to its orbit around the sun. This tilt is responsible for the changing seasons as different parts of the Earth receive varying amounts of sunlight throughout the year.

Answer 3

No. It remains at a tilt, which gives us the seasons.

Answer 4

It is tilted 23.5o.
