行星在冷矮星上的轨道距冷矮星更近,因此运行周期也就更短---这就需要天文学家频繁的观察。
The habitable zone for planets in orbit around cool dwarf stars is also much closer in, so the period of revolution is shorter — affording astronomers more frequent transits to observe.
它的运行轨道为近似的圆形,以229天为周期,围绕着两个恒星作轨道运行,这个行星位于这个系统的可居住区之外——所谓可居住区,那里有液体水,正像我们所知道的那样,那里可能会有生命的存在。
Traveling on a nearly circular, 229-day orbit around both host stars, the planet lies outside the system's habitable zone—the region where liquid water, and thus life as we know it, could exist.
路易斯安那大学拉斐特分校的天文学家约翰·马泰塞和丹尼尔·惠特迈尔曾多次发表声明表示,基于长周期彗星运行轨道的不规则性,他们发现了该天体存在的证据。
Astronomers John Matese and Daniel Whitmire of the University of Louisiana at Lafayette repeatedly claimed to have evidence of its existence based on irregularities among long-period comets.
