'''HD 73526'''是一颗[[黄矮星]]（G6V），位于大约323[[光年]]之外的[[船帆座]]中。<br />
<br />
== 恒星 ==<br />
这颗恒星比太阳更冷、更亮，质量相近，而体积更大。它比太阳的年龄大22%，[[金属量]]几乎是太阳的两倍，因为其中富含[[铁]]。<br />
<br />
== 行星系 ==<br />
2002年时发现了一颗2.1倍[[木星质量|M<sub>J</sub>]]的行星[[HD 73526 b]]围绕它公转，轨道只比进行绕太阳的轨道略近一些。<ref>{{cite journal | url=http://www.iop.org/EJ/article/0004-637X/587/1/423/56381.html | author=Tinney ''et al.'' | title=Four New Planets Orbiting Metal-enriched Stars | journal=The [[Astrophysical Journal]] | volume=587 | issue=1 | year=2003 | pages=423–428 | doi=10.1086/368068 | last2=Butler | first2=R.
