'''HD 89744 b'''是一顆屬於[[離心木星]]的[[太陽系外行星]]，母恆星是 [[HD 89744]]<ref name="Korzennik2000">{{cite journal | url=http://www.iop.org/EJ/article/1538-4357/533/2/L147/005046.html | author=Korzennik ''et al.'' | title=A High-Eccentricity Low-Mass Companion to HD 89744 | journal=The [[Astrophysical Journal]] Letters | year=2000 | volume=533 | issue=2 | pages=L147–L150 | doi=10.1086/312611 | last2=Brown | first2=Timothy M. | last3=Fischer | first3=Debra A. | last4=Nisenson | first4=Peter | last5=Noyes | first5=Robert W. | bibcode=2000ApJ...533L.147K|arxiv = astro-ph/0003045 }}</ref>。

在橫跨1000萬年的模擬中，該行星會清除除了接近8:3共振區域以外的軌道附近物質。因此這表示沒有其他行星在它的母恆星適居帶內。觀測結果也排除了公轉週期1年以內，超過0.7倍木星質量的行星<ref name="Wittenmyer2007">{{cite journal | url=http://www.iop.org/EJ/article/1538-3881/134/3/1276/205882.html | author=Wittenmyer ''et al.'' | year=2007 | title=Dynamical and Observational Constraints on Additional Planets in Highly Eccentric Planetary Systems | journal=The [[Astronomical Journal]] | volume=134 | issue=3 | pages=1276–1284 | doi=10.1086/520880 | last2=Endl | first2=Michael | last3=Cochran | first3=William D. | last4=Levison | first4=Harold F. | bibcode=2007AJ....134.1276W | arxiv=0706.1962 | access-date=2012-11-22 | archive-date=2020-03-12 | archive-url=https://web.archive.org/web/20200312063205/https://iopscience.iop.org/article/1538-3881/134/3/1276/205882.html | dead-url=no }}</ref>。
