'''HD 83443'''是一颗位于[[船帆座]]中的[[橙矮星]]，距离太阳系大约142[[光年]]。截止2000年，至少有一颗已确认的[[太阳系外行星]]围绕其公转。

== 行星系 ==

它的行星[[HD 83443 b]]是由[[米歇尔·麦耶]]领导的[[日内瓦系外行星探测小组]]于2000年发现的。<ref>{{cite web | title=Exoplanets Galore! | url=http://www.eso.org/public/outreach/press-rel/pr-2000/pr-13-00.html | date=4 May 2000 | work= | publisher=European Southern Observatory | accessdate=2 August 2009 | deadurl=yes | archiveurl=https://web.archive.org/web/20090228024326/http://www.eso.org/public/outreach/press-rel/pr-2000/pr-13-00.html | archivedate=2009年2月28日 }}</ref>它的最小质量与[[土星]]的质量相当，轨道是已知最靠近恒星的之一，只有地球到太阳距离的1/25。它只需要三天时间就能公转一周。这颗[[热木星]]可能半径比木星略大。

在发现第一颗行星的同一年，日内瓦的研究人员又宣布发现了另一颗行星，编号依惯例为“HD 83443 c”。它的质量比行星b略小，轨道半长轴很短，[[轨道离心率|离心率]]很大。<ref>{{cite web | title=European Southern Observatory: Six Extrasolar Planets Discovered | url=http://www.spaceref.com/news/viewpr.html?pid=2365 | date=7 August 2000 | work= | publisher=SpaceRef Interactive Inc. | accessdate=2 August 2009 }}</ref>它的公转周期大约为28.9天。这十分有趣，因为这表明两颗行星之间存在10:1的[[轨道共振]]。然而，另一个由天文学家[[R·保羅·巴特勒]]带领的团队没有检测到任何表明第二颗行星存在的迹象。<ref>{{cite journal | url=http://www.iop.org/EJ/article/0004-637X/578/1/565/55830.html | author=Butler ''et al.'' | title=On the Double-Planet System around HD 83443 | journal=The [[Astrophysical Journal]] | volume=578 | issue=1 | year=2002 | pages=565–572 | doi=10.1086/342471 | last2=Marcy | first2=Geoffrey W. | last3=Vogt | first3=Steven S. | last4=Tinney | first4=C.
