An easy short google search says 23.5 degrees is the Earth's tilt.

This is an example of someone cherry-picking data to fit a narrative. -- The Earth's speed varies slightly throughout the year due to the elliptical shape of Earth's orbit, ranging from about 66,616 mph at aphelion (farthest point from the Sun) to 68,000 mph at perihelion (closest point to the Sun). -- The polar circles are two imaginary lines of latitude on Earth that mark the boundaries of the polar regions, The Arctic Circle is located at approximately 66°33′47.5″ north latitude, and the Antarctic Circle is at 66°33′47.5″ south latitude. -- The axial tilt varies slowly over a cycle of about 41,000 years, oscillating between 22.1 and 24.5 degrees. -- The rate of curvature for a sphere is defined by its Gaussian curvature, which is constant at every point on the surface and equal to the reciprocal of the square of its radius, K= 1/r^2. This means the curvature is highest at the center of the sphere and decreases as the radius increases.
