註釋 (Tsù-sik)[修改]

  1. ↑ 5-minute exposure taken by the William Herschel Telescope on 28 October; ʻOumuamua appears as a light source in the center of the image， while background stars appear streaked due都the speed of ʻOumuamua as the telescope tracked一。 (英語)[1]
  2. ↑ Objects on hyperbolic trajectories have negative semimajor axis， giving them a positive orbital energy。 (英語)
  3. ↑ Range at which the object was expected都be observable。 Brightness peaked at 19.7 mag on 18 October 2017， and faded below 27.5 mag (the limit of Hubble Space Telescope for fast-moving objects) around 1 January 2018。 By late 2019， it should have dimmed都34 mag。 (英語)
