How much mass does the sun lose every year?
Can you be more precise ? It is not difficult to estimate how much energy goes away in the form of light, and that is easy to convert into mass terms, but the sun also looses mass by other processes, less under control and more difficult to estimate.Lacero said:How much mass does the sun lose every year?
http://curious.astro.cornell.edu/question.php?number=563 [Broken]Plugging this into the above formula tells us that the Sun loses around 4,200,000,000 kilograms every second!
Here is one scenario for the sun's evolution - http://www.astronomy.ohio-state.edu/~pogge/Ast162/Unit6/futuresun.htmlPhy6explorer said:Does the statement that the Sun is losing mass mean that it is losing the content of Hydrogen and Helium in it? I mean, isn't Hydrogen and Helium what makes up the Sun's mass?
I mean since the Sun makes up the maaaajor (major,I mean,Just to indicate the vastness of its majority) part of the Solar system's mass, is the Sun's loss of mass going to affect us in any way? Forgive me if its a dumb question.
malawi_glenn said:yes if the sun looses mass, the radii of the planets orbits will be slightly changed. But there is no danger. When the sun blows up to become a red giant, however, things can happen ;-).

Phy6explorer said:Amazing!I still have a question? Do you think that if the heat slowly reduces in the sun the reaction will slow down and the sun will not lose as much mass? Helium is formed by four protons fusing but what about hydrogen?How is hydrogen present in the sun?I also read that around 75% of the sun consists of hydrogen.What impact does hydrogen throw on the Sun? Does is also fuse and is less heavier than what made it and contribute to the sun's loss of mass or does it do something else?Awesome explanation!Thanks!
