How many years does it take for heat generated in the sun's core to reach its outer layer,the photoshere?

To be honest, no one is really quite sure. There is some amount of speculation based on models, and the theories produce answers that range from 10,000 years to several million years.





The reason that heat and light take so long to travel from the sun's core to the photosphere is because the energy is absorbed by an atom, then re-radiated only to be absorbed by another atom and re-radiated again. The number of atoms are astronomical (please pardon the pun) and even when the photon of energy is radiated, it isn't always towards the photosphere. Sometimes it is back towards the core. So even at the speed of light, it takes a very very long time for a photon of energy to travel from atom to atom all the way to the surface.How many years does it take for heat generated in the sun's core to reach its outer layer,the photoshere?

I don't know. Can you tell us?
hundreds of lightyears
About 4.
It takes well over 200,000 years for the heat from the core of the sun to reach the photosphere. From there it's few minutes to earth.
A million years or so. That's how long it takes energy originally appearing as gamma radiation in the core to random walk its way to the photosphere.
