6P/d'Arrest
Sign in to save'''6P/d'Arrest (also known as d'Arrest's Comet or Comet d'Arrest''') is a periodic comet orbiting between Mars and Jupiter once every 6.54 years. It is the second of three comets discovered by German astronomer, Heinrich Ludwig d'Arrest. It next comes to perihelion 1.35 AU from the Sun on March 31, 2028, when it is expected to brighten to around apparent magnitude 11.

'''6P/d'Arrest (also known as d'Arrest's Comet or Comet d'Arrest''') is a periodic comet orbiting between Mars and Jupiter once every 6.54 years. It is the second of three comets discovered by German astronomer, Heinrich Ludwig d'Arrest. It next comes to perihelion 1.35 AU from the Sun on March 31, 2028, when it is expected to brighten to around apparent magnitude 11.
== Observational history == It was first observed by Heinrich Ludwig d'Arrest, in Leipzig, Germany, between June 28–30, 1851. In 1991, a study conducted by Andrea Carusi and Giovanni B. Valsecchi (Istituto Astrofisica Spaziale, Rome), alongside Ľubor Kresák and Margita Kresáková (Slovak Astronomical Institute, Bratislava) independently suggested that this comet is the same as the comet previously observed by Philippe de La Hire in 1678.
