5D/Brorsen (Lost)
Comet 5D/Brorsen, also known as Comet Brorsen, was a periodic comet belonging to the Jupiter family of comets, which is now considered a lost comet. It was first discovered by the Danish astronomer Theodor Brorsen on February 26, 1846. Based on the collected observations, the comet had an orbital period of 5.46 years and traveled around the Sun in an eccentric orbit with the closest approach to the Sun (perihelion) at a distance of about 0.58 astronomical units (AU), and the farthest distance (aphelion) at around 5.6 AU. The latest successful observations of Comet 5D/Brorsen were conducted during the 1879 apparition, while it was not possible to find the comet again during any of the subsequent apparitions.
5D/Brorsen (Lost) is currently in the constellation of Bootes.
The current Right Ascension of 5D/Brorsen (Lost) is 14h 14m 32s and the Declination is +16° 16’ 17” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current estimated magnitude of 5D/Brorsen (Lost) is 9.43 (JPL).
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.

5D/Brorsen (Lost) Distance from Earth
The distance of 5D/Brorsen (Lost) from Earth is currently 105,098,450 kilometers, equivalent to 0.702540 Astronomical Units. Light takes 5 minutes and 50.5707 seconds to travel from 5D/Brorsen (Lost) and arrive to us.
The following chart shows the distance of 5D/Brorsen (Lost) 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 5D/Brorsen (Lost) from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of 5D/Brorsen (Lost) to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of 5D/Brorsen (Lost) to Earth happens on Tue Oct 26 2083 at a distance of 0.259836 Astronomical Units, or 38,870,982 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
5D/Brorsen (Lost) Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of 5D/Brorsen (Lost), 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.
