The Sun contains very nearly all of the matter within that area, and the solar wind which I assume you're getting confused with a gigantic sauna is made up almost entirely of photons and electrons, which have effectively no mass. The heliosphere is created primarily by the Sun's magnetic field, not the Sun shooting gas everywhere like a popped balloon.
The Earth and everything else is heated by sunlight, the various radiation waves produced by the Sun, not directly by the Sun's surface like it was a campfire. There's nothing between the Earth and the Sun to do that.
Magcargo is about twice as hot as the Sun's surface, around 10000C. Unlike a nuclear explosion, where temperatures can briefly reach several million degrees at the epicenter, Magcargo is always this temperature, so it's constantly radiating this level of heat at everything around it. It's at about 3 times the melting point of Tungsten, so it's more than hot enough to melt the ground underneath it. With the amount of energy it's releasing it would be white-hot and bright enough to blind you, and anything within some tens of meters would spontaneously ignite from the heat.
