Pluto: The Dwarf Planet That Stole Our Hearts

For 76 years, Pluto was the ninth planet in our solar system. Discovered in 1930 by Clyde Tombaugh, it captured the imagination of generations. That all changed in 2006 when the International Astronomical Union reclassified Pluto as a "dwarf planet" — but that hasn't diminished our love for this distant world!

🎮 GAME CONNECTION

In Orbit Defender, you protect Pluto from the Kuiper Belt objects that share its orbital neighborhood — the very reason it was "demoted"! Your 5 moon shields (Charon, Nix, Hydra, Kerberos, and Styx) help you survive the onslaught. It's Pluto's revenge against the cosmos!

Why Pluto Matters

Despite its reclassification, Pluto remains scientifically fascinating. NASA's New Horizons mission in 2015 revealed a world far more complex than anyone imagined — with ice mountains, nitrogen glaciers, and most famously, the heart-shaped Tombaugh Regio that charmed the world.
