## Main Question or Discussion Point

Hi guys, so I know the sun is losing mass because it is radiating energy away. This leads me to wonder about some things - I have been trying to figure out what the mass of the sun was ~4.5 billion years ago (current age of the sun).

Also I am interested in knowing what the mass will be ~6.5 billion years from now, when it is entering the white dwarf stage.

Does anyone know it? Or know how to figure it out? I am assuming it involves an exponential decay function, because of the familiar relationship between luminosity and mass.

Thanks!
