Predicted light curve

Comet C/2014 A4 (SONEAR) predicted light curve showing magnitude as a function of time:

Data is sampled with a 2 days interval, so there might be inaccuracies for objects which change brightness very rapidly (for instance for comets when they are close to perihelion). Also, for comets there might be in general large discrepancies between the observed and predicted brightness because of the their highly dynamic behaviour.

Maximum and minimum distances from Earth and Sun

Max and min distances between Comet C/2014 A4 (SONEAR) and Sun and Earth between 2013-Jan-01 and 2025-Jan-01.

  • Minimum distance from Earth: 3.20346403 au (479,231,399 km) on 2015-Oct-19
  • Maximum distance from Earth: 22.08870823 au (3,304,423,725 km) on 2024-Dec-22
  • Minimum distance from Sun: 4.18047329 au (625,389,904 km) on 2015-Sep-06
  • Maximum distance from Sun: 21.48259887 au (3,213,751,055 km) on 2025-Jan-01

Note: values are sampled with 1 day interval, there might be high inaccuracies for the minimum distance from the Sun for objects which move very fast when close to perihelion.
