It is over 1.3 million kilometres across with a mass of around 2 million trillion trillion kilograms. The Sun formed around 4.5 billion years ago and will remain stable for another four billion years, at which point it will become a red giant. The Sun is spectral type G2, with a luminosity class of V. It radiates energy due to nuclear fusion in its core, with the energy released equivalent to 400 trillion trillion watts. The Sun has an atmospheric temperature of 5778 Kelvin. Its spectrum has neutral and ionized metal lines, especially ionized calcium lines.
