Stephenson 2-18 is currently the largest known star in the universe. This is also the most luminous red supergiants we know of (with a surface temperature of 3,200 K, it shines with about 440,000…
While the diameter of our Milky Way is one million light-years, the Andromeda Galaxy is about two million light-years. We have an estimated 10,000 billion stars and more than 600 billion Earth-like planets. There are a trillion stars that are two million light-years across. So how many there look like Earth ??.
