The earth's inner core is the earth's innermost part. it is primarily a solid ball with a radius of about 1,220 km (760 miles), which is about 70% of the moon's radius.[1][2] it is composed of an iron–nickel alloy and some light elements. the temperature at the inner core's surface is approximately 5,700 k (5,430 °c), which is about the temperature at the surface of the sun. 

First of all you would die.   do not try this at home but back to the question.   there are six parts of the sun.   from the outside to the inside: corona, chromoshpere, photosphere, convective zone, radiative zone, and the core.   then use the dictionary or reliable sources such as wikipedia to find out what they do.   good luck.
