2006 RH120是一颗直径大约5米的近地小行星的临时名字,它通常都是绕着太阳公转,但是大约每20年左右会接近地月系统一次。
除了通常看到的月亮,地球还有一个临时的“月亮第二”,也在以小行星的形式围绕地球旋转,2006 RH120就是这样的“迷你月亮”。

2006 RH120发现背景

编辑
月球由于自转和公转的特点,始终以同一侧面面向地球。这一面相对光滑,拥有古老岩浆形成的较平坦、黑暗的低矮平地。上世纪60年代,天文学家借助航天器发现远离我们的月亮“背面”的秘密,那里布满崎岖山脉和火山口。美国加州大学的艾瑞克·阿斯帕和瑞士伯恩大学的马丁·彻奇希在2011年8月发表在《自然》上的文章中提出,通过研究发现,在远古时期,地球已拥有两个月亮,其中一个非常微小,另一个则是我们今天看到的月球。二者发生低速碰撞后合二为一,因此形成了月球今天的外貌。这个理论可以用来解释为什么探测器发现月球背面与面朝地球的一面会有如此大的差异。而在此之前,曾有科学家指出,月球背面与面朝地球一面之所以不同,只是由于引力的作用所致,而不是碰撞的结果。
天文专家认为,月球起源于太阳系形成早期,是一颗火星大小的天体碰撞地球后产生的碎片在重力作用下形成的。2011年8月,科学期刊《自然》又刊登了一篇文章,提出一个月球起源新观点:月球背面之所以与面向地球那一面外貌相去甚远,正是因为它与另一个“月亮第二”相撞的结果。
科学家称,当地球围绕太阳旋转,经过微小的小行星的时候,地球的引力将可能捕获它们。当它们当中的一个被吸引,围绕地球旋转时,当它的旋转轨道不规则地摇摆着,与月亮轨道重合时,它会被对方猛烈撞击,最终脱离地球的吸引,回到外太空。有研究小组甚至观察到,自2006年9月开始至2007年7月,就曾经有一颗临时小行星围绕地球旋转了将近一年的时间。[1]

2006 RH120天文数据

编辑
2006RH120是在亚利桑那州图森市卡特琳娜天空观测站被发现到的,被命名为2006RH120,估计直径只有5米。它通常都是绕着太阳公转,但是每20年左右会接近“地月系”一次。“2006RH120能够被发现,是因为它比其他的‘临时月亮’更大一点,后来大部分进入到地球轨道的小行星都只有大约1米宽。

2006 RH120运动特点

编辑
偶尔这个天体会短暂的进入临时卫星捕获(temporary satellite capture,TSC),在临时卫星捕获期间,流星体可以是除了月球之外的另一颗天然卫星。2006RH120在临时轨道上打转几个循环,然后就打包一走了之的几个轻如鸿毛的小不点是卫星。2006RH120在2006年9月到2007年7月是在地球轨道上的小不点,直到2008年2月18日才给了小行星的名称,就是所知的6R10DB9,卡特林那巡天系统的内部辨识名称。

2006 RH120来源争议

编辑
2006RH120的来源仍存在着一些争议。发现后,因为他的大小、轨道和光谱——符合农神五号火箭使用的钛白氧化涂料——而没有给予正式的名称,建议它可能是一个人造的物体。存在的一个先例是几乎在完全一样轨道上的J002E3,目前认为它是阿波罗12号的农神S-IVB第三节的助推器。[2]
