Wandering planets don’t wander! Scientists have discovered that wandering planets revolve around sta-xhero

Rogue planets do not stray! Scientists found wandering planets orbiting stars running a number for the 2MASS J2126 (art sketch) the planet has been considered a wandering planet, but astronomers recently surprised to find that in fact it is around a star revolution, just between the two is very far away, a distance of more than 1 trillion kilometers in more than 7000 times the distance of the planet and the distance between the two stars like the earth is about 104 light-years away. Here is the image on the left shows the sky. The right side is a local enlargement, marking the star TYC 9486-927-1 and the roughly position of the planet 2MASS J2126 running around it. The light from the TYC 9486-927-1 takes a month to reach the 2MASS J2126, and the distance between the planets is amazing. Map of earth taken from space, the warmth of the sun from the sun shines on this planet we live Sina Technology News Beijing on February 4th news, according to foreign media reports, the so-called "rogue planets" refers to those independent in space to run the "abandoned" lonely planet. However, a recent discovery by astronomers suggests that the situation may not be so simple: these stray planets may actually be running around a star – just a little distance between the two. Astronomers were surprised to find that a wandering planet named 2MASS J2126 actually runs around a star, but the distance between them is more than 1 trillion kilometers! That’s more than 7000 times the distance between the earth and the sun! From the point of view of planetary distances, such distances are staggering. It takes about 8 and a half minutes for the light from the sun to reach the earth, and it takes about 5.5 hours to reach the farthest Pluto in the solar system known as the most distant object of the celestial body. By contrast, however, the light from the star that it turns around reaches the surface of planet 2MASS J2126, which takes about a month! Dr. Nair Niall Deacon of University of Hertfordshire, UK, is the head of the international team responsible for the study. "This is the most distant planetary system ever discovered," he said. In fact, the star and the planet involved have been known to astronomers for 8 years, but none of them have been linked together." He said, "after all, the planet is not as lonely as we thought it was, but there is no doubt that it’s a long way to go." In the past 5 years, scientists have continued to find a few rogue planet. But unlike the earth, these exotic worlds are like gas giants like jupiter. But despite their massive mass, Jupiter, like Jupiter, does not have enough mass to reach the threshold of nuclear fusion, so that nuclear fusion is not possible to become a star and glow. 2MAS)

流浪行星不流浪!科学家发现流浪行星绕恒星运行   一颗编号为2MASS J2126(艺术示意图)的行星一直被认为是流浪行星,但天文学家们近日惊讶地发现,实际上它正围绕一颗恒星公转,只是两者之间相距极为遥远,距离超过1万亿公里,相当于日地距离的7000倍以上   这颗行星和恒星两者距离地球一样远,都是104光年左右。这里左侧图像展示的是这两者所在的天区。右侧是局部放大图,标出了恒星TYC 9486-927-1以及正在绕它运行的行星2MASS J2126的大致位置。   从TYC 9486-927-1发出的光需要一个月才能抵达2MASS J2126,从行星公转距离的角度来说,这样的间距着实是惊人的。图为从太空拍摄的地球,来自太阳的温暖阳光照耀在我们生活的这颗星球之上   新浪科技讯 北京时间2月4日消息,据国外媒体报道,所谓“流浪行星”是指那些独立在太空中运行的“被遗弃”的孤独行星。然而近日天文学家们的一项发现却表明情况可能并没有那么简单:这些流浪行星实际上可能仍然是在围绕某颗恒星运行的――只是两者之间的距离有点遥远。   天文学家们极其惊讶地发现一颗编号为2MASS J2126的流浪行星,实际上却围绕着一颗恒星在运行,只不过两者之间的距离竟然超过了1万亿公里!这相当于地球到太阳之间距离的7000倍以上!   从行星公转距离的角度来说,这样的间距着实是惊人的。   从太阳发出的光抵达地球大约需要8分半钟,抵达太阳系中为大众所熟知的天体中最遥远的冥王星则大约需要5个半小时。然而相比之下,从它绕转的恒星发出的光,抵达行星2MASS J2126的表面则大约需要整整一个月的时间!   英国赫特福德大学的奈尔・迪肯(Niall Deacon)博士是作出这项研究工作的国际小组负责人。他表示:“这是迄今发现的间距最为遥远的行星系统。实际上这里面涉及的这颗恒星以及这颗行星都是早在8年之前就已经为天文学界所知了,但从没有人将这两者联系在一起。”他说:“这颗行星毕竟不像我们之前所认为的那样孤独,但毫无疑问这个公转的距离是相当遥远的。”   在过去的5年间,科学家们陆陆续续发现了几颗流浪行星。但和地球不同的是,这些异域世界都是类似木星那样的气态巨行星。但尽管体积质量巨大,但同样和木星一样,它们的质量还不足以达到点燃核聚变反应的门槛,无法发生内部核聚变燃烧而成为一颗恒星并发光。   2MASS J2126此前在一次美国天文学家们进行的红外波段巡天工作中被首次发现,当时美国同行们将其描述为一个“疑似低质量天体”。   随后在2014年,加拿大科学家们确认这颗天体的年龄足够年轻,质量足够小,因此可以被归入流浪行星的范畴。   迪肯的研究团队注意到流浪行星2MASS J2126运行的区域距离一颗年轻的恒星TYC 9486-927-1非常近,两者距离地球大约都是104光年左右。他们意识到这两者之间似乎存在着某种联系。随后开展的更加详尽的研究表明这两颗天体不属于任何已知的年轻恒星星团体系。   之后,天文学家们成功估算出了行星2MASS J2126的质量大约相当于木星的11.6倍~15倍,这样的质量数将其置于行星与被称作“褐矮星”的失败恒星之间的位置。   天文学家们也注意到一个惊人的事实,那就是这颗行星实际上正在围绕着这颗恒星运行,但公转一周的时间,也就是这颗行星上一年的长度竟然相当于地球上的90万年!实际上,我们可以估算得到这样一个结果,那就是自从这颗行星诞生至今,对它而言一共只过去了50年。   天文学家们相信行星2MASS J2126的表面应该不会存在任何生命,但如果这颗行星上真的有居民的话,那么从他们的角度看去,他们的“太阳”最多只是天空中一个比其他星星稍稍明亮一些的光点。   研究组中的另一名成员,澳大利亚国立大学的西蒙・墨菲(Simon Murphy)博士表示:“这样一个间距如此巨大的行星系统究竟是如何形成并保留下来的?这仍然是一个开放性的问题。”   有关这项研究的详细论文已经刊载于本月出版的《皇家天文学会月报》(MNRAS)。(晨风)相关的主题文章:
