Which famous stars are cited as examples of Red Supergiants regarding their immense radii?
Answer
Betelgeuse or Antares.
The red supergiant class includes some of the most visually impressive and physically largest known stars in the universe, often possessing radii hundreds of times that of our own Sun. To illustrate this colossal physical volume, the text specifically names Betelgeuse and Antares as prime examples belonging to this category. These stars showcase the extreme end of stellar evolution for high-mass objects, where their radii can be so vast that they would easily extend past the orbits of outer planets like Jupiter or even Saturn if placed where our Sun resides, offering a stark contrast to the more modestly sized red giants.
