Comet C/2020 S8 (Lemmon) Distance from Earth
The distance of Comet C/2020 S8 (Lemmon) from Earth is currently 305,611,526 kilometers, equivalent to 2.042887 Astronomical Units. Light takes 16 minutes and 59.4103 seconds to travel from Comet C/2020 S8 (Lemmon) and arrive to us.
The following chart shows the distance of Comet C/2020 S8 (Lemmon) from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of C/2020 S8 (Lemmon) from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Comet C/2020 S8 (Lemmon) to Earth
Between January 2013 and December 2100, the closest approach of Comet C/2020 S8 (Lemmon) to Earth happens on Fri Apr 23 2021 at a distance of 1.418795 Astronomical Units, or 212,248,688 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet C/2020 S8 (Lemmon) brightness
The observed magnitude and coma diameter values are derived from the Comet Observers Database by averaging the values reported in recent observations (more recent than 4 days), when available. The Estimated Magnitude comes from the JPL Horizons ephemerides service and might be inaccurate given the highly dynamic and unpredictable behavior of comets. When available, please refer to the Observed Magnitude value and consider the Estimated Magnitude as a directional indication. We acknowledge with thanks the comet observations from the COBS Comet Observation Database contributed by observers worldwide and used in this table to report recent comet observations.
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet C/2020 S8 (Lemmon), according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
Comet C/2020 S8 (Lemmon) rise and set times
The rise and set times are defined as the time at which the upper limb of Comet C/2020 S8 (Lemmon) touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
