Earth 90 Degree Tilt 2025 Earth. The earth, just like all the planets of the solar system (except mercury), has a rotation axis that is titled with respect to its orbit around the sun. How does the earth's tilt affect.
Earth’s axis is currently tilted 23.4 degrees, or about half way between its extremes, and this angle is very slowly decreasing in a cycle that spans about 41,000 years. The earth’s spin axis is tilted 23.5° with respect to the ecliptic, giving moderate seasons and preventing temperature extremes anywhere on the planet.
