8P/Tuttle
Sign in to save8P/Tuttle (also known as '''Tuttle's Comet or Comet Tuttle''') is a periodic comet with a 13.6-year orbit. It fits the classical definition of a Jupiter-family comet with an orbital period of less than 20 years, but does not fit the modern definition of (2 Jupiter< 3). Its last perihelion passage was 27 August 2021 when it had a solar elongation of 26 degrees at approximately apparent magnitude 9. Two weeks later, on September 12, 2021, it was about from Earth which is about as far from Earth as the comet can get when the comet is near perihelion.

8P/Tuttle (also known as '''Tuttle's Comet or Comet Tuttle''') is a periodic comet with a 13.6-year orbit. It fits the classical definition of a Jupiter-family comet with an orbital period of less than 20 years, but does not fit the modern definition of (2 Jupiter Under dark skies, the comet was a naked-eye object. On December 30, 2007, it was in close conjunction with the Triangulum Galaxy. On January 1, 2008, it passed Earth at a distance of . It was visible telescopically to Southern Hemisphere observers in the constellation Eridanus throughout February 2008.
Predictions that the 2007 Ursid meteor shower could have possibly been stronger than usual due to the return of the comet, did not appear to materialize, as counts were in the range of normal distribution.
