Type: Hyperbolic Perihelion date: 11 June 2022 Perihelion distance (q): 1.8 Aphelion distance (Q) : n/a Period (years): n/a Eccentricity (e): 1.00 Inclination (i): 112.6 JPL orbit diagram COBS lightcurve The Zwicky Transient Facility reported observations of a 20th magnitude possible NEO made on 9 March 2021 with the 1.2m Oschin Schmidt. This was placed on the PCCP as ZTF0Kij and subsequently found to show cometary features by astrometrists. It could reach 11th magnitude around the time of perihelion when it will be at high southern declination.
