This was the first comet discovery of 1994 and Kushida's second discovery within a month. It last came to perihelion on 25 January 2024, and brightened to about magnitude 10.Yoshida +144P/Kushida closest Mars approach on 2119-May-18jpldata Date & time ofclosest approach Mars distance(AU) Sun distance(AU) Velocitywrt Mars(km/s) Velocitywrt Sun(km/s) Uncertaintyregion(3-sigma) Reference 2119-May-17 11:19 ± 13 minutes 0.049 AU e6km e6mi LD unit on 1.68 AU e6km e6mi unit 13.6 28.6 ± 13 thousand km Horizons Based on data gathered during the period of January 9–11, 1994 Syuichi Nakano calculated the date of perihelion to be 1993 December 5.33 and the distance of perihelion as 1.36 AU. The low inclination to the ecliptic suggested to Nakano that the comet could be a short period type. On January 14, 1994, Daniel W. E. Green confirmed Nakano's suggestion and published a short-period orbit on IAU Circular 5922. Based on 29 positions obtained during the period of January 9–13, Green determined a perihelion date of 1993 December 12.99, a perihelion distance of 1.37 AU, and an orbital period of 7.20 years. Using over 300 positions obtained between January 7 and July 9, 1994, Patrick Rocher refined the calculations and determined the perihelion distance as 1.367 AU, the perihelion date as 1993 December 12.862, and the orbital period as 7.366 years.
