Ursa Minor (cave) Ursa Minor (cave) Ursa Minor Cave is part of Sequoia National Park, a naturally formed system of caves in California's Sierra Nevada. The cave was discovered in August 2006 by four cave explorers from the Cave Research Foundation who found a softball-sized hole on a cliff face in the mountains. After widening the hole to allow for human entry, the explorers discovered one of the most spectacular caves in the western United States. The cave has since been named "Ursa Minor," because of the large bear skeleton found in the cave. The cave was featured in the September 2007 issue
Ursa Major I Dwarf −6.75, meaning that it is less luminous than some stars, like Deneb in the Milky Way. It is comparable in luminosity to Rigel. It has been described as similar to the Sextans Dwarf Galaxy. Both galaxies are ancient and metal-deficient. It estimated to be located at a distance of about 330,000 light-years (100 kpc) from the Earth. That is about twice the distance to the Large Magellanic Cloud; the largest and most luminous satellite galaxy of the Milky Way. There was another object called "Ursa Major Dwarf", discovered by Edwin Hubble in 1949. It was designated as Palomar 4. Due
