[00:00:00]Here's what would happen if Betelgeuse replaced our sun. This star is so enormous that you could squeeze 1 billion suns into it. Betelgeuse is a red supergiant near the end of its life, roughly 15 times the mass of the sun and about 700 times its width. It's so enormous that if you dropped it into the center of our solar system, well, its outer layers would reach past Earth's orbit and likely far beyond Mars. Some estimates even put it past Jupiter's orbit, depending on how its size is measured. First, if Betelgeuse replaced the sun, well, Earth wouldn't just keep calmly orbiting like normal.
