'''HD 114762'''是一顆暗星，位於[[后髮座]]，距離地球約98[[光年]]，其[[恒星光谱分类|光譜類型]]為F9V，[[視星等]]為7.3，[[肉眼]]不可見，需借助雙筒望遠鏡觀測。<br />
<br />
==行星系統==<br />
1989年，David Latham用多普勒偵測法在這顆恆星發現了一顆行星。它與恆星的距離約0.3個[[天文單位]]，質量約為[[木星]]的11倍，其公轉週期約為84天。<br />
<br />
根據[[紅外線]]偵測估計，該行星的外觀呈藍色，與[[海王星]]相似，半徑與木星差不多，表面溫度介乎453K-642K之間，衛星的質量上限約為10個[[地球]]。<br />
