↑ 2018 AG37 was first announced at a conference in February 2019, but was not officially announced by the MPC until 10 February 2021. Precovery images of it date back to January 2018.
↑ The celestial coordinates of 2018 VG18 tại thời điểm khám phá là 04h 49m 36.353s +18° 53′ 10.69″.[1] See Taurus for constellation coordinates.
↑ In the convention for minor planet provisional designations, the first letter represents the half-month of the year of discovery while the second letter and numbers indicate the order of discovery within that half-month. In the case for 2018 VG18, the first letter 'V' corresponds to the first half-month of November 2018 while the succeeding letter 'G' indicates that it is the 7th object discovered on the 19th cycle of discoveries. Each completed cycle consists of 25 letters representing discoveries, hence 7 + (18 completed cycles × 25 letters) = 457.[16]
↑ The longitude of pericenter is the sum of the argument of pericenter (ω) and the longitude of ascending node (Ω) of the orbit of a body. For 2018 VG18's orbit, ω=16.75° and Ω=245.36°,[5] thus 16.75° + 245.36° = 262.11°. For Sedna's orbit, ω=311.53° and Ω=144.33°,[12] thus 311.53° + 144.33° = 455.86° or 95.86°. The difference between Sedna's and 2018 VG18's longitude of perihelion is about 198°: 455.86° – 262.11° = 193.75°.
