Actually, the entire solar system is inside the Heliosphere, which would be more acurately described as being inside the sun's INFLUENCE than inside the Sun itself.
Scientists are actually collecting data about the boundary of the heliosphere right now from Voyager, which is in the process of crossing over the heliopause into the interstellar medium. This is exciting to them because before this, the properties of the bow shock, heliopause, heliosheath, etc could only be calculated from known data.
Once completely outside of the solar winds, Voyager will be the first manmade object to measure the interstellar medium and report to us what the weather's like out there. We don't know what sort of energetic particles, radiation, etc there are out there - at least not for certain. It won't be long before we know for sure.
Voyager is crossing out into true space, somewhat analagous to the transition from the atmosphere to interplanetary space.
Having said all of that, the plasma from our sun that reaches regions like the earth is very hot indeed - luckily, the material is of extremely low density, so there's not much of it to transfer its incredible heat into spacecraft.

Technically, the solar wind is not part of the sun (as we define the sun).
Its true, the earth (and the rest of the solar system out to the Kuiper Belt) are within the influence of the solar wind and also the sun's gravity.
But the sun's boundary is defined as being at the photosphere of the sun, and that does not extend even to the orbit of Mercury.

Since the Sun has a large atmosphere and even larger magnetic field, that depends on where you stop defining the Sun. We usually stop at the photosphere, about 93 million miles from the Earth.

Yes. Well technically the earth's atmosphere extends to infinity. So the entire universe is part of the earth! Just a lesson not to allow yourself to get to hung-up on semantics and technicalities.

Let's leave all this techinal crap. God, the Creator, placed earth at just the right distance from the sun or else all life on earth would be annihalted. Or am I from another planet or galaxy?

No, we revolve around the sun with the other planets.
But there are other planets and suns also .
The sun would melt the earth if we were inside it.

Not so...WRONG.
The surface temperature of the Sun is 10,000 degrees F.
The surface temperature of the Earth ranges from about -20 degrees to +120 degrees F.

Did not know that. How can that be?
EDIT: Thank you Ryan and especially zerobyte for enlightening us. Yes, it is interesting.
