Major celestial events of 2017:     Aug. 12‐13: Perseid meteor shower Produced from the debris of the comet Swift‐Tuttle — first observed in 1862 — the Perseids are one of the best meteor showers largely due to its intensity, which reaches up to 60 meteors per hour at its peak. The shower is observed annually from July 17 to Aug. 24 but the intensity is at its highest on the night of Aug. 12 and the morning of Aug. 13.
