A STAR IS AN OBJECT THAT PRODUCES IT OWN ENERGY INCLUDING HEAT AND LIGHT

ASTRONOMERS LIKE TO LIST THE DISTANCE RO OBJECT WITHIN OUR SOLAR SYSTEM (PLANETS,DWARF,ASTROIDS,

A LITTLE BIT OF MASS IS LOST WHEN HYDROGEN PARTICLES COMBINE TO MAKEE HALIAM

THE SUN ACCOUNTS FOR 99.86 OF THE MASS IN THE SOLAR SYSTEM.THE SUN IS TRAVELING AT 220KM PER SECOND

THE POSITION OF THE SUN IN THE SKY IS A FUNCTION OF BOTH TIME AND GEOGRAPHIC CORTINATE OF THE OBSERVER ON THE SURFACE OF THE SUN

THE SUN IS A HUGE ,GLOWING SPHERE OF HOT GAS.MOST OF THIS GAS IS HYDROGEN (ABOUT 70%) AND HALIAM( ABOUT 28%).

THE CORE OF THE SUN IS THE REGION THAT EXTENDS FROM THE CENTER TO ABOUT 20-25% OF THE SOLAR RADIUS

COMPARED TO THE AMOUNT OF TIME IT TAKES TO THROUGH THE RADIATIVE ZONE,ENERGY IS TRANSPORTED VERY QUICKLY THROUGH THE OUTER CONVECTIVE ZONE.

WHEN CHARGED PARTICLES FROM THE SUN STRIKE ATOMES IN EARTHS ATMOSPHERE,THEY CAUSE ELECTRONS IN THE ATOMS TO MOVE TO A HIGHER STATE.

THIS REACTION KNOWN AS NUCLEAR FUSION,CONVERTS HYDROGEN ATOMS INTO HALIAM.

EACH OF THE LETTERS OF E=mc2 STANDS FOR FOR A PARTICULARLY PHYSICAL QUANTITY.
