'''HIP 41378'''是位於[[巨蟹座]]，距離[[地球]]346[[光年]]的一顆[[恆星]]。這顆恆星的視星等為8.92等。這顆F型主序星的質量為{{Solar mass|1.15}}，半徑為{{Solar radius|1.25}}。它的表面溫度約為{{val|6,251|fmt=commas|ul=K}}.

== 行星系統 ==
2016年，[[克卜勒太空望遠鏡#第二道光 (K2)|K2克卜勒任務]]在HIP 41378周圍發現了五顆行星，其大小從地球的2倍到[[木星]]的大小不等，最外層的行星距離母恆星約1天文單位<ref name="Vanderburg"/>。直到2019年獲得K2[[上普羅旺斯天文台]]的徑向速度數據後，才知道半長軸。此外，還發現了第六顆非凌日行星，HIP 41378 g，以及其它行星可能存在於HIP 41378g和HIP41378d之間的猜測。HIP 41378 f行星也被發現可能有光學上較厚的環或高度延伸的大氣層<ref name=santerne /><ref>{{Cite journal|last1=Akinsanmi|first1=B.|last2=Santos|first2=N.
