Has anyone ever landed on the sun?

Answer 1

NO!!!

It is not possible to land on the sun as it has no actual surface, it is a ball of plasma (hot ionized gas) all the way through. Via the solar wind and solar flares the sun actually reaches far beyond the planets and into the Oort Cloud, if not further. The 2 Voyager spacecraft are just leaving the outer reaches of the Sun's ball of plasma now. The temperature of this plasma is as follows:

1. core, 15.7 MK
2. radiative zone, 7 MK to 2 MK
3. convective zone, 2 MK to 5800 K
4. photosphere, 5800 K (this is often mistakenly called the surface, but it is just the layer we see)
5. temperature minimum, 4100 K
6. chromosphere, 4100 K to 20000 K
7. transition region, 20000 K to 1 MK
8. corona, 1 MK to 20 MK
9. heliosphere, supersonic solar wind and solar flares (all the planets, etc. are in this part of the sun)
10. heliosheath, solar wind begins slowing here
11. heliopause, this is the point where the solar wind slows to subsonic speeds
12. heliotail, the sun's gases merge into the galaxy's gases here

Answer 2

No, landing on the sun is not possible due to its extremely high temperatures and lack of a solid surface. All attempts to land on the sun would result in immediate destruction of any spacecraft or equipment due to the intense heat and radiation present.
