Comet 201P/LONEOS
Comet 201P/LONEOS is currently in the constellation of Virgo. The current Right Ascension of Comet 201P/LONEOS is 13h 19m 28s and the Declination is -08° 56’ 38” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current estimated magnitude of Comet 201P/LONEOS is 25.98 (JPL).
Summary of key facts about Comet 201P/LONEOS [tip: you can also create a Quick Access page for this data if you access it frequently and would like to have a simpler view]:
- 201P/LONEOS is above the horizon from Greenwich, United Kingdom [change].
- It is visible looking in the West-South-West direction at an altitude of 13° above the horizon.

Comet 201P/LONEOS Distance from Earth
The distance of Comet 201P/LONEOS from Earth is currently 762,597,261 kilometers, equivalent to 5.097648 Astronomical Units. Light takes 42 minutes and 23.7507 seconds to travel from Comet 201P/LONEOS and arrive to us.
The following chart shows the distance of Comet 201P/LONEOS 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 201P/LONEOS from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Comet 201P/LONEOS to Earth
Between January 2013 and December 2100, the closest approach of Comet 201P/LONEOS to Earth happens on Tue Nov 26 2097 at a distance of 0.367929 Astronomical Units, or 55,041,372 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 201P/LONEOS brightness
The current visual magnitude of Comet 201P/LONEOS is 25.98.
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 201P/LONEOS, 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 201P/LONEOS 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 201P/LONEOS 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 201P/LONEOS 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.
