WISEPA J025409.45+022359.1 förkortat till WISE J0254+0223, är en ensam stjärna belägen i den norra delen av stjärnbilden Valfisken. Den har en skenbar magnitud av ca 15,92^[2] (J) och kräver ett ktaftfullt teleskop med kamera för att kunna observeras. Baserat på uppmätt parallax på ca 146,1^[5] mas beräknas den befinna sig på ett avstånd av ca 22 ljusår (ca 6,8 parsec) från solen.

Observation

WISE J0254+0223 upptäcktes 2011 från data som samlats in av Wide-field Infrared Survey Explorer (WISE)-satelliten — NASA:s rymdteleskop med infraröd våglängd på 40 cm, vilket uppdrag pågick från december 2009 till februari 2011. WISE J0254+0223 har två upptäcktsdokument: Scholz et al. (2011) och Kirkpatrick et al. (2011) (det första publicerades tidigare).^[6]^[1]

Scholz et al. upptäckte två sena bruna dvärgar av T-typ, bland andra WISE J0254+0223, med hjälp av preliminära data från WISE och uppföljande nära-infraröd spektroskopi med LUCIFER1 nära-infraröd kamera/spektrograf vid Large Binocular Telescope (LBT).
Kirkpatrick et al. presenterade upptäckten av 98 nya funna av WISE bruna dvärgar med komponenter av spektraltyperna M, L, T och Y, bland vilka också var WISE J0254+0223.^[1]
