Stellar Size Comparison: KY Cygni, Betelgeuse, and Solar System Orbits #1689771 (License: Personal Use)

The image visually compares the colossal diameters of red supergiants KY Cygni (1,500 times the Sun’s size) and Betelgeuse against the relative scale of the inner solar system, where Mars and Jupiter’s orbits are shown as concentric circles around the Sun. KY Cygni dominates the right side, illustrating how even the largest planetary orbits pale in comparison to hypergiant stars. The stark black background emphasizes the luminous gradients of the stars and orbital paths.

Used in astronomy education,科普 articles, or space-themed websites to convey stellar scale; matches user intent seeking intuitive understanding of star sizes versus planetary systems.
