Distance of Comet 45P/Honda-Mrkos-Pajdusakova from Earth
The following chart shows the distance of Comet 45P/Honda-Mrkos-Pajdusakova from Earth as a function of time. Distance data is measured in Astronomical Units and sampled with a 2 days interval.
The reported distances might be inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 45P/Honda-Mrkos-Pajdusakova is also available as a real time updated value in the Live Position and Data Tracker.
Light Curve of Comet 45P/Honda-Mrkos-Pajdusakova
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 45P/Honda-Mrkos-Pajdusakova, 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.
