It is roughly 100,000 times brighter than the Sun but significantly cooler, with a surface temperature of approximately 3,600 Kelvin (6,020°F).
If placed at the center of our solar system, it would engulf the orbits of Mercury, Venus, Earth, and Mars, likely extending past Jupiter's orbit .
Betelgeuse is a , meaning its brightness fluctuates over time.
In late 2019 and early 2020, it experienced a historic drop in brightness, eventually attributed to a massive surface mass ejection that cooled into an obscuring dust cloud.
