The observed values of Magnitude, Coma Diameter and Tail Length are derived from the most recent observation recorded at the Comet Observers Database. The value of Predicted Magnitude comes from the JPL Horizons ephemerides service and, in the case of comets, might be inaccurate given the highly dynamic and unpredictable behavior of these objects. When available, please refer to the Observed Magnitude value and consider the Predicted 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 40P/Vaisala Distance from Earth
The distance of Comet 40P/Vaisala from Earth is currently 847,155,251 kilometers, equivalent to 5.662883 Astronomical Units. Light takes 47 minutes and 5.8057 seconds to travel from Comet 40P/Vaisala and arrive to us.
The following chart shows the distance of Comet 40P/Vaisala 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 40P/Vaisala from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet 40P/Vaisala to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Comet 40P/Vaisala to Earth happens on Mon Mar 24 2070 at a distance of 0.879460 Astronomical Units, or 131,565,362 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 40P/Vaisala Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 40P/Vaisala, 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.
