(2607) Yakutia is an asteroid of the main inner belt that was discovered by the Soviet astronomer Nikolai Tschernych on July 14, 1977 at the Crimean Observatory in Nautschnyj ( IAU code 095). There had already been several unconfirmed sightings of the asteroid: May 25, 1951 under the provisional designation 1951 KK at the Goethe Link Observatory in Indiana and in August 1966 (1966 PN) at the Boyden Observatory near Bloemfontein .
The asteroid belongs to the Nysa group, a group of asteroids named after (44) Nysa (also called the Hertha family, after (135) Hertha ). The timeless (non- osculating ) orbital elements of (2607) Yakutia are almost identical to those of five smaller ones, if one considers the absolute brightness of 15.3, 16.4, 16.6, 18.2 and 18.4 compared to 13, 6, asteroids: (14908) 1993 OQ 4 , (104274) 2000 EU 274 , (139179) 2001 FT 137 , (457646) 2009 BD 190 and 2005 ST 44 .
The mean diameter of (2607) yakutia was calculated to be 4.711 (± 0.051) km and the albedo to be 0.280 (± 0.049).
The asteroid was named after the Yakut ASSR on December 1, 1982 , today's Sakha Republic .
