As thermonuclear fusion proceeds in its core, the Sun
Chapter 13, Problem 77(choose chapter or problem)
As thermonuclear fusion proceeds in its core, the Sun loses mass at a rate of 3.64 3 109 kg/s. During the 5 000-yr period of recorded history, by how much has the length of the year changed due to the loss of mass from the Sun? Suggestions: Assume the Earths orbit is circular. No external torque acts on the EarthSun system, so the angular momentum of the Earth is constant.
