La Estrella de Van Maanen (VMa 2 / GJ 35 / WD 0046+051)^[7] ye una nana blanca na constelación de Piscis, asitiada al oeste de δ Piscium y al este de ω Piscium. De magnitú aparente +12,4,^[7] ye demasiáu tenue pa ser visible a simple vista, pero puede ser reparada con un telescopiu de 150-200 mm d'apertura o con telescopios más pequeños forníos con una cámara CCD. Afayóse nel añu 1917 pol astrónomu Adriaan van Maanen quien, comparando fotografíes tomaes ente los años 1914 y 1917, notó'l so eleváu movimientu propiu añal (2,98").^[8]
