'''HD 1461 e'''，或稱為'''天倉增十九e'''，是一個環繞視星等6等[[黃矮星]][[天倉增十九]]的可能存在的[[系外行星]]，位於[[鯨魚座]]，距離地球約76光年。<br />
<br />
==概要==<br />
它的[[質量下限]]介於13.1到32.7倍地球質量。它的軌道半長軸是1.165天文單位，[[軌道離心率]]0.74。該行星可能是類似[[天王星]]或[[海王星]]的[[類木行星]]，於2009年12月14日由[[凱克天文台]]和[[澳洲天文台|英澳天文台]]以[[都卜勒光譜學|徑向速度法]]發現<ref name="disco-rivera">{{cite arXiv |last=Rivera |first=Eugenio |authorlink= |eprint=0912.2566 |title=<br />
