For nuclear fusion.
The temperature at the Sun's inner core is estimated to be around 15 million degrees Celsius. This high temperature is necessary to sustain the nuclear fusion reactions that power the Sun.
A high mass star's core collapses when nuclear fusion ceases and gravitational pressure overwhelms the radiation pressure supporting the core. This collapse leads to a rapid increase in temperature and pressure, triggering a supernova explosion.
Thermonuclear reactions in the Sun take place only in its core because the core has high temperatures and pressures that are necessary for nuclear fusion to occur. The extreme conditions in the core provide the energy needed to overcome the repulsive forces between atomic nuclei and allow them to fuse together.
The high temperature of the Sun's core is necessary for nuclear fusion to occur. Fusion reactions at this temperature produce the tremendous amount of energy that allows the Sun to shine and sustain life on Earth.
The outer core is liquid. Its pressure is low enough and its temperature high enough for it to melt. The inner core is solid. Both its pressure and temperature are higher than the outer core, but the increased pressure overwhelms the increased temperature, keeping the inner core from melting.
Only at the core where the temperature and pressure is high enough.
For nuclear fusion.
yes your core will always stay at 98.6 but your surace temperature changes with the temperature alround you. for example if you are in a cold place your surface temperature will be cold. if in a hot area your surface temperature will be hot. the only time your core temperature changes is if your sick or if you been been exposed to a low or high temperature for an exteneded period of time. i hope that is clear enough
The outer core is not solid, it is liquid.

Because of the core
The inner core is solid, even though it has a high temperature, because of the high pressure in the center of Earth.
The temperature of Mercury's core has not yet been determined. The surface temperatures are very high because of the closeness of the sun.
The Earth's inner core is solid because of the immense pressure from the layers of rock and metal above it, which keeps the inner core's temperature high enough to maintain a solid state despite being made mostly of iron and nickel.
