如果您认为地球只有一个月亮,请再三思。研究人员透露,我们的星球实际上可能在任何给定时间都有一个绕我们绕行的整个收集。
一项新的研究发现,地球在轨道上至少有六个“最小值”的基础,其中大多数是实际的月球,我们每天晚上都在天空中看到了
class。芬兰和瑞典说,这些微小的卫星的直径通常约为六英尺,是通过影响月球表面的小行星形成的。碰撞基本上踢了一堆灰尘和月球垃圾,其中有些足够大,有足够的大量将其拉入地球上的p The study suggested that these broken moon pieces, known as 'lunar ejecta,' can move into somewhat stable orbits, staying near Earth for years.
Minimoons typically stay in Earth's orbit only for a short time before escaping or, in rare cases, hitting our planet or the moon.
Most of the time, these temporarily bound objects (TBOs) break away from Earth and are pulled into the sun's gravity, where they'll remain indefinitely, while new chunks of the moon are broken off to replace them.
Robert Jedicke, a researcher at the University of Hawaii, said: It's 'kind of like a square dance, where合作伙伴定期改变,有时会离开舞池一段时间。 src =“ https://i.dailymail.co.uk/1s/2025/07/23/21/89734729-14934111-ASTEROID_2024_PT5_WILL_WILL_ERTER_ERTER_ERTER_ERTER_ERTER_ERTER_ERTER_ERTER_ERTH_ERTH_SS_AS_AS_AS_AS_AS_AS_A_MINII_MINII_MINI_MOON_SS-FFROM_FROM_FROM_FOROM_FOROM_FOROM_FOROM_FOROM_SPP.高度=“ 424” width =“ 634” alt =“ 2024 PT5从9月29日至2024年11月25日(库存图像)” class =“ class =“ blkborder img-share” style =“ max-width:max-width:100%” load =“ lazy lazy”> class =“ lazy> class =”> 2024 pton ote' 29至2024年11月25日(库存图像)
',鉴于18%的TBO也可以归类为Minimoons,我们的名义结果表明,[Earth-Moon System]在[Earth-Moon System]中应大约有6.5个微小的tbo,在[Earth-Moon System]中的任何时间都大于1 M,”研究者在他们的新报告中写道。
这项新研究可以颠覆科学家之间的信念,即这些悄悄地绕地球的最小人物全部来自太阳系的小行星皮带。
2018年的研究表明,大多数TBO都表明,这个遥远的地区来自这个遥远的地区。 class="mol-para-with-font">However, the new findings published in Icarus looked at two recently discovered minimoons, Kamo'oalewa and 2024 PT5, which both appear to have telltale signs of being moon fragments.
Specifically, Kamo'oalewa, discovered in 2016 by the Pan-STARRS1 telescope in发现夏威夷,发现以与月亮的表面成分相匹配的方式反映光。
大小imoon,直径在131至328英尺之间,也具有相同的lunar岩石组成,也具有相同的硅胶。
Jedicke告诉Space.com,在2024年8月7日进入地球轨道的2024 PT5在2024年被发现,曾表现出相同的Lunar Like特征。

Last year, 2024 PT5 was dubbed Earth's temporary 'second moon' because of its size and lingering presence so close to our planet.
Astronomers collected data on the supposed asteroid as it circled Earth, which led astronomers to suggest that it may have been a chunk of our moon instead.
The leading theory of lunar formation is called the 'giant impact hypothesis,' which theorizes that the moon is actually an enormous, orbiting hunk of Earth.
According to this theory, our planet collided with a Mars-sized planet roughly fo您的数十亿年前,这引发了地球上的材料的爆炸爆炸,这些材料爆发到太空中,并最终凝结形成月亮。
如果巨大的影响假设和2024 PT5的分析是正确的,那将意味着我们的真实月亮是这个微型的月球和它的祖先的祖先。
