Force of Light and Solar Pressure on Earth
The Sun’s light exerts measurable mechanical pressure on Earth, estimated around 70 000 tons. A sphere’s surface grows with radius squared while mass grows with radius cubed, so as objects shrink the light pressure declines slower than gravity, implying extremely small bodies could be repelled by sunlight.
