144P/Kushida is a periodic comet discovered in January, 1994, by Yoshio Kushida at the Yatsugatake South Base Observatory in Japan. This was the first comet discovery of 1994 and his second discovery within a month.
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.
