Comet 205P/Giacobini Distance from Earth
The distance of Comet 205P/Giacobini from Earth is currently 268,981,282 kilometers, equivalent to 1.798029 Astronomical Units. Light takes 14 minutes and 57.2250 seconds to travel from Comet 205P/Giacobini and arrive to us.
The following chart shows the distance of Comet 205P/Giacobini 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 205P/Giacobini from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Comet 205P/Giacobini to Earth
Between January 2013 and December 2100, the closest approach of Comet 205P/Giacobini to Earth happens on Tue Aug 22 2028 at a distance of 0.609784 Astronomical Units, or 91,222,329 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 205P/Giacobini 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.
Comet 205P/Giacobini rise and set times
The rise and set times are defined as the time at which the upper limb of Comet 205P/Giacobini 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.
