For the other comet discovered by Ferdinand Quénisset, see C/1893 N1 (Rordame–Quénisset).

Comet Quénisset, also known by its modern formal designation C/1911 S2, is a non-periodic comet that has a 4,000-year retrograde orbit around the Sun. It is the second of two comets discovered by French astronomer, Ferdinand Quénisset.[1]

Potential meteor shower

Orbital calculations by J. B. Dale revealed that although there would be no close encounter between the comet and the Earth, the former's descending node resulted in a minimum orbit intersection distance of about 0.0172 AU (2.57 million km) by 16 December 1911.[4] This has led to other scientists predicting a meteor shower originating from this comet that will be coming from the constellation Vulpecula on April 27 of each year, though none has been observed so far.[5]
