Comet 153P/Ikeya-Zhang Distance from Earth

The distance of Comet 153P/Ikeya-Zhang from Earth is currently 5,398,040,577 kilometers, equivalent to 36.083673 Astronomical Units. Light takes 5 hours, 5.9252 seconds to travel from Comet 153P/Ikeya-Zhang and arrive to us.

The following chart shows the distance of Comet 153P/Ikeya-Zhang 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 153P/Ikeya-Zhang from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest approach of Comet 153P/Ikeya-Zhang to Earth

NOTE: values for the closest approach are computed with a sampling interval of 1 day.

Comet 153P/Ikeya-Zhang brightness

The current visual magnitude of Comet 153P/Ikeya-Zhang is 35.21.

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 153P/Ikeya-Zhang, 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 153P/Ikeya-Zhang rise and set times

Today's Comet 153P/Ikeya-Zhang rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

The rise and set times are defined as the time at which the upper limb of Comet 153P/Ikeya-Zhang 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.
