6P/d'Arrest is a periodic comet in our Solar System, orbiting between Mars and Jupiter. It passes 53 Gm from the Earth, about a third of the Earth-Sun distance, on August 9, 2008.
In 1991, Andrea Carusi and Giovanni B. Valsecchi (Istituto Astrofisica Spaziale, Rome), and Ľubor Kresák and Margita Kresáková (Slovak Astronomical Institute, Bratislava) independently suggested this comet was the same as a comet observed by Philippe de La Hire in 1678.
