NGC 2371-2 is a dual lobed planetary nebula located in the constellation Gemini. Visually, it appears like it could be two separate objects; therefore, two entries were given to the planetary nebula by John Louis Emil Dreyer in the New General Catalogue, so it may be referred to as NGC 2371, NGC 2372, or variations on this name.[1] It has also been called the double bubble nebula.[2]

The central star of the planetary nebula has a spectral type of [WO1], indicating a spectrum similar to that of an oxygen-rich Wolf–Rayet star.[3]
Observations
NGC 2371-2 is in the constellation of Gemini which is visible in the latitudes between +90° and −60°. The planetary nebula appears southwest of Castor, and is located at a distance of 4400 light years.
At 13th magnitude, this nebula is well within the limits of most amateur telescopes. Like most planetary nebulae, this one responds well to both high magnification and narrow-band filters, especially an OIII emission filter. It is listed within the RASC's 110 Finest NGC List.[4]

NGC 2371 ist ein planetarischer Nebel im Sternbild Zwillinge, der etwa 4300 Lichtjahre von der Erde entfernt ist.- [en] NGC 2371-2
[es] NGC 2371
NGC 2371 es una nebulosa planetaria en la constelación de Géminis. Tiene doble entrada en el Nuevo Catálogo General, por lo que lo tanto NGC 2371 como NGC 2372 se refieren a ella. También recibe el nombre de nebulosa Gemini. Dado su diámetro de sólo 0,9 arcmin, para su observación es recomendable un telescopio con más de 100 aumentos. Fue descubierta en 1785 por William Herschel e identificada como una nebulosa por Don Pease en 1917.[ru] NGC 2371
