Comet 157P/Tritton
Comet 157P/Tritton is currently in the constellation of Sextans. The current Right Ascension of Comet 157P/Tritton is 10h 22m 12s and the Declination is -09° 40’ 13” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current estimated magnitude of Comet 157P/Tritton is 20.32 (JPL).
Today's rise, transit and set times of Comet 157P/Tritton from Greenwich, United Kingdom [change] (all times relative to the local timezone Europe/London):
- 157P/Tritton is above the horizon from Greenwich, United Kingdom [change].
- Right now it is placed in the South-South-West direction at an altitude of 23° above the horizon.

Comet 157P/Tritton Distance from Earth
The distance of Comet 157P/Tritton from Earth is currently 221,645,830 kilometers, equivalent to 1.481611 Astronomical Units. Light takes 12 minutes and 19.3309 seconds to travel from Comet 157P/Tritton and arrive to us.
The following chart shows the distance of Comet 157P/Tritton 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 157P/Tritton from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet 157P/Tritton to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Comet 157P/Tritton to Earth happens on Sun Dec 14 2092 at a distance of 0.559012 Astronomical Units, or 83,626,991 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 157P/Tritton Brightness
The current visual magnitude of Comet 157P/Tritton is 20.32.
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 157P/Tritton, 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.
