Comet 217P/LINEAR will make its closest approach to the Sun, at a distance of 1.23 AU.
From Ashburn (click to change) however, it will not be observable – it will reach its highest point in the sky during daytime and will be no higher than 20° above the horizon at dawn.
For more information about its path across the sky, see In-The-Sky.org's ephemeris page for comet 217P/LINEAR.
This event was automatically generated on the basis of orbital elements published by the Minor Planet Center (MPC), and is updated daily (last update, 19 Jul 2018).
Note that the future positions of comets are typically known with a high degree of confidence, but their brightnesses are often much more unpredictable, since it is impossible to predict with certainty how they will respond as they move closer to the Sun. Magnitude estimates should be assumed to be highly provisional more than a few weeks in advance.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
