WebDec 30, 2024 · As the axis is not perpendicular to the plane of Earth’s orbit (it presently makes an angle of about 23.4 ), gravity from the sun exerts a net torque on the Earth’s rotation axis, causing it to precess with a period of about 25000 years. Consequently, the current polar star will only remain the polar star for a couple of centuries. WebFeb 27, 2024 · This angle is determined by both properties of the solid and the liquid and the interaction and repulsion forces between liquid and solid and by the three phase interface properties (gas, liquid and solid). Those …
