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 8P/Tuttle from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest approach of Comet 8P/Tuttle to Earth

Between January 2013 and December 2100 the closest approach of Comet 8P/Tuttle to Earth happens on Mon Dec 28 2048 at a distance of 0.17536714 Astronomical Units, or 26,234,550 kilometers:

Comet 8P/Tuttle brightness

The current visual magnitude of Comet 8P/Tuttle is 31.21.

31.21

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 behvior 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 8P/Tuttle, 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 8P/Tuttle rise and set times

Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London

Today's Comet 8P/Tuttle rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 60.4°
Max altitude: 68.0°
Azimuth: 299.5°
Comet 8P/Tuttle is below the horizon from Greenwich, United Kingdom

The rise and set times are defined as the time at which the upper limb of Comet 8P/Tuttle touches the horizon, consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
