When the sun goes down over the horizon, we can still see the sun because the light of the sun is bent by our atmosphere. I would imagine that if one were outside of our atmosphere on the far side of earth away from the sun, yet in a path in line with that light they would also see the sun (even though the sun were technically blocked from their view in a straight geometric line), due to this lensing effect of our atmosphere. Although the sun has no 'atmosphere' exactly, there is still a lot of mass streaming out from it such as hydrogen and helium, and so therefore doesn't it have some optical bending properties? My question here is this: If the sun is to be considered having an 'atmosphere' in any sense that can bend light, how does this affect the results that 'proved' einstein's relativity experiment where light from stars passing behind the sun during an eclipse 'emerged' early from behind the sun? Do the results need to be adjusted for solar atmospheric effects of any such effect if there are any?
