{{efn|name=perihelion|[[Apsis#Time of perihelion|Perihelion passage]]: Given perihelion is still 10 years away and the orbit is highly eccentric, an [[曆元|epoch]] closer to 2031 will give a more accurate estimated perihelion date that better accounts for continuing planetary [[攝動|perturbations]]. The [[噴射推進實驗室小天體資料庫|JPL SBDB]]'s epoch 2016 unperturbed [[二體問題|two-body]] solution (Sun+comet) gives a date of 2031-Jan-21. But properly integrating the orbit with [[噴氣推進實驗室線上曆書系統|JPL Horizons]] to perihelion passage accounts for all planetary perturbations and gives a date of 2031-Jan-23.}}

{{efn|name=epoch1950|1=For epoch 1950-Jan-01 orbit period is "PR= 9.99E+08 / 365.25 days" = ~2.7 million years. In 1950 the comet was still 95 AU from the Sun and had not entered the planetary region of the Solar System.}}

{{efn|name=epoch2100|1=For epoch 2100-Jan-01 orbit period is "PR= 1.61E+09 / 365.25 days" = ~4.4 million years. In 2100 the comet will be 84 AU from the Sun and will have exited the planetary region of the Solar System.}}
