(7341) 1991 VK is a near-Earth minor planet in the Apollo group. It was discovered by Eleanor F. Helin and Kenneth J. Lawrence at the Palomar Observatory in California on 1 November 1991. It is listed as a potentially hazardous object.[1] Every five years (from 1946 through 2091) the asteroid makes a close approach to the Earth.[3] The most recent close approach to Earth was on 25 January 2022 at a distance of 0.064 AU (9,600,000 km; 5,900,000 mi).[3]
The object is suspected of displaying cometary activity.[4][5]
