At over 1.4 million kilometers (869,919 miles) wide, the sun contains 99.86 percent of the mass of the entire solar system: well over a million Earths could fit inside its bulk.
The total energy radiated by the Sun averages 383 billion trillion kilowatts, the equivalent of the energy generated by 100 billion tons of TNT exploding each and every second.
