497593 Kejimkujik is a main-belt minor planet,[1][2] first observed on 1 May 2006 by Paul Wiegert at the Mauna Kea Observatories.[3] It was designated 2006 JU69, and later received the secondary designation 2010 CY119.[4][5][3][6] Kejimkujik is about 1.2 miles (1.9 km) across and can be seen only with professional telescopes.[2]
Naming
On 13 June 2022, the International Astronomical Union approved the name Kejimkujik for minor planet 497593.[1][4][2] It is named after Kejimkujik National Park in Nova Scotia, Canada, which is recognized for its natural and cultural significance and its designation as a Dark Sky Preserve by the Royal Astronomical Society of Canada in 2010.[1][7][2] The naming proposal was supported by members of the Royal Astronomical Society of Canada and representatives of the Acadia First Nation.[1] Its SPKID is 20497593.[5]
Orbital elements
Kejimkujik orbits the Sun in the main asteroid belt, with a perihelion of approximately 2.77 AU and an inclination of roughly 4.925° with respect to the ecliptic. Of the fifteen "Nova Scotia Asteroids" named after people or places connected to Nova Scotia, it has the least orbital eccentricity – about 0.03, which is nearly circular.[8] It completes one orbit around the sun in approximately 4.85 years.[5][9]
