Star Eats A Whole Planet- Its cause!!

                                                       Star "Eats" A Whole Planet 
Scientists have found evidence of a plant's Destruction. The team thinks that its star gradually expanded and ate it up. It is bound to happen to all stars. All stars have hydrogen for their fuel. Take and example of our star. Our sun converts 5 million tonnes of hydrogen to 3.7 million tonnes of helium ( remaining 1.3 million tonne into Light and energy) every second. It has been doing this for 5 billion years and continue doing it until 5 billion years more. But Once its hydrogen fuel is exhausted, it will burn helium. Helium evolves more heat during combustion. So heat will try to escape from Sun's gravity. To stop this Sun will expand. Which will reduce its temperature considerably. But the distance between Earth and Sun will be reduced so earth's temperature will rise to 10,000 degree Celsius. It will lead to utter destruction of earth.
