Ursa Minor may be associated with gamma-ray source 3EG J1621+8203, which has high-energy gamma-ray emission. It is also noted for its one-sided radio jet—one of the brightest known—discovered in 1977. The Ursids, a prominent meteor shower that occurs in Ursa Minor, peaks between December 18 and 25. Its parent body is the comet 8P/Tuttle. Ursa Minor Ursa Minor (Latin: "Lesser Bear", contrasting with Ursa Major), also known as the Little Bear, is a constellation in the Northern Sky.

Taken from the villain in "The Magnificent Seven", Calvera is the nickname given to an X-ray source known as 1RXS J141256.0+792204 in the "ROSAT All-Sky Survey Bright Source Catalog" (RASS/BSC). It has been identified as an isolated neutron star, one of the closest of its kind to Earth. Ursa Minor has two enigmatic white dwarfs. H1504+65 is a faint (magnitude 15.9) star that with the hottest surface temperature—200,000 K—yet discovered for a
