We know that the sun is a star and if it explodes it will be known as a supernova. The explosion will be very bright and powerful. The dust released from the explosion will result in make of more stars and planets. That’s how our solar system was made. When the sun explodes, there won’t be light and the planets that are close to the sun will also be destroyed. These planets include Mercury, Venus, and Earth. Once a supernova is formed other existing planets will turn colder as the temperature of the sun reduces.
