While we know our sun loses mass via radiant light, heat and solar wind, is not the sun also gaining mass from objects (such as asteroids, meteorites) and energy (such as radiant light, heat, or other cosmic analogous particles from other solar systems) every second? Is there a way to measure this?

Dear Richard,

At the moment, we cannot measure these things in other solar systems as well as we can with our own. But spacecraft in the future might enable us to do better!
