(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 5 years (from 1946 through 2091) the asteroid makes a close approach to the Earth.^[3] The most recent close approach to Earth was on Jan 25, 2017; the next close approach will be on Jan 25, 2022 at a distance of 0.064 AU (9,600,000 km; 5,900,000 mi).^[3]
