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: 2.85943154 au (427,764,871 km) on 2015-Oct-16
  • Maximum distance from Earth: 22.31338985 au (3,338,035,616 km) on 2024-Dec-12
  • Minimum distance from Sun: 3.82835299 au (572,713,457 km) on 2015-Sep-11
  • Maximum distance from Sun: 21.67798734 au (3,242,980,754 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.
