|- bgcolor = "#FFFAFA" HD 210702 is an orange subgiant star located approximately 179 light-years away in the constellation of Pegasus. With a mass of 1.8 times that of the Sun, the star spent its main-sequence life as an A-type star. The visual luminosity is 11.38 times that of the Sun and it is 182.4 light years away. The magnitude is near the naked-eye limit, but binoculars can easily see it. The star shows variability in its radial velocity consistent with a planet-mass companion in a Keplerian orbit,〔 and one was duly discovered in April 2007, from observations at Lick and Keck Observatories in Mount Hamilton (California) and Mauna Kea (Hawai'i), USA. == See also == * HD 175541 * HD 192699 * List of extrasolar planets 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HD 210702」の詳細全文を読む スポンサード リンク
