Discovery of Pluto's Moons Nix and Hydra
On October 31, 2005, astronomers announced the discovery of two new moons orbiting Pluto, named Nix and Hydra. This discovery was made possible through images taken by the Hubble Space Telescope, enhancing our understanding of the complex system surrounding the dwarf planet. Nix, named after the Greek goddess of the night, and Hydra, named after the nine-headed serpent, provide valuable insights into the formation and evolution of celestial bodies in our solar system.
Fun fact. Nix and Hydra are approximately 50 and 60 kilometers in diameter, respectively.
