75 Ceti is a G-type giant with at least one planet.〔 In Chinese, (), meaning ''Circular Celestial Granary'', refers to an asterism consisting of α Ceti, κ1 Ceti, λ Ceti, μ Ceti, ξ1 Ceti, ξ2 Ceti, ν Ceti, γ Ceti, δ Ceti, 75 Ceti, 70 Ceti, 63 Ceti and 66 Ceti. Consequently, 75 Ceti itself is known as the Tenth Star of Circular Celestial Granary.〔 (AEEA (Activities of Exhibition and Education in Astronomy) 天文教育資訊網 2006 年 7 月 11 日 )〕 The planet's discoverers consider this planet b "typical" of gas giants.〔 Note that (like many recorded planets) b takes in much more insolation than does Jupiter and, indeed, Earth.〔Square root of luminosity means that an Earth like planet would have to be >7 AU from the star.〕 There may be additional periodic factors in the data, corresponding to ''m'' sin ''i'' of around and , at distances of ∼0.9 AU and ∼4 AU. If these are confirmed, they are more irradiated than Earth as well. ==References== 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「75 Ceti」の詳細全文を読む スポンサード リンク
