Every Star That Could Swallow A Planet Explained In 17 Minutes

The Sun It is the only star known with certainty to be on course to consume a planet, and the planet is Earth. It is an ordinary yellow main-sequence star, roughly 4.6 billion years old, converting hydrogen into helium in its core at a rate of about 600 million tons per second. That process is stable, and it has held the Sun almost unchanged across the entire history of complex life on Earth. But it is not permanent. A star fuses hydrogen only until the core runs out, and when the Sun's core is exhausted, in about 5 billion years, the balance that holds the star together will fail.
