(5001) EMP (1952 RF,1977 EN4,1982 KQ3,1987 SB1) main belt mid-region asteroid imaged on the first night of the 2022 November talcos. While photographing the Apollo asteroid (177614) 2004 HK33, this came into the same picture. The asteroid was discovered by American astronomer Edward LG "Ted" Bowell (b.1943) at Anderson Mesa Station (699) of the Lowel Observatory on September 19, 1987. The asteroid got its name from the Russian ephemeris of Minor Planets book, "Ehfemeridy Malykh Planet" (EMP). The asteroid has a size of 9.72 km and a rotation speed of 26.3919 h/r. When photographing, the asteroid was at a distance of 1.6093au and at its closest on October 21, 2022 at 1.496au.
