Montes Secchi (Latin for "Secchi Mountains") is a minor range of lunar mountains located near the northwestern edge of Mare Fecunditatis. This roughly linear formation of low ridges grazes the northwestern outer rim of the crater Secchi, the formation from which this range gained its name (the crater is named after Pietro Secchi, a 19th-century Italian astronomer). The ridges trend from southwest to northeast. The distinctly triangular Secchi Theta is better known by its original name, "Mount Marilyn"; it was named in 1968 by Apollo 8 astronaut Jim Lovell, after his wife.〔(Defending Mount Marilyn ): Astronauts Want Moon Landmark Names Recognized, by Robert Z. Pearlman, SPACE.com Editor, October 09, 2013 04:54pm ET〕 The selenographic coordinates of the range midpoint are 3.0° N, 43.0° E, and they lie within a diameter of 50 km. This is smaller than the diameter of the crater Taruntius, located to the northeast of the mountains. ==Gallery== Image:Montes Secchi as08-13-2342hr.jpg|Oblique view facing west from Apollo 8 Image:Mount Marylin and A10 CSM AS10-28-4165HR.jpg|'Mount Marilyn' is in upper left, with Apollo 10 CSM at right 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「Montes Secchi」の詳細全文を読む スポンサード リンク
