This Near-Earth Asteroid was discovered in 1998 by the LINEAR survey and followed for one month. But by 2003, five years later, it had not been re-observed and was in danger of becoming lost. SPACEWATCH® observers Anne S. Descour and Arianna E. Gleason recovered 1998 VS with the SPACEWATCH® 1.8-meter telescope (MPC site code 291) in 2003, 5 years after it had been last observed and had acquired a long uncertainty line of variation. Without that, it may have remained lost and would never have become a Yarkovsky candidate when again re-observed in March 2019, this time by site code T12, the 2.2-meter telescope on Mauna Kea, Hawaii.
