Hydra II

Hydra II is a dwarf galaxy orbiting the Milky Way within the Hydra constellation. Discovered in 2015, it is classified as an ultra-faint dwarf galaxy due to its extremely low luminosity and stellar content. This galaxy is located at around 154,000 light-years from Earth. Hydra II has a small size, with a radius of approximately 68 light-years and an absolute magnitude of about -5.8. Its stars are predominantly old and metal-poor, typical characteristics of dwarf galaxies. The galaxy's low luminosity and distinct properties make it a compelling object for studying the dynamics and formation of dwarf galaxies within the galactic halo.
