一项新的研究揭示了Theia, 形成月球的行星, 很可能来自地球附近的太阳系内部。 A new study reveals Theia, the planet that formed the Moon, likely came from the inner Solar System near Earth.

《科学》的一项新研究发现,Theia是火星大小的身体,与早期地球相撞形成月球,很可能起源于内部太阳系,比地球更靠近太阳。 A new study in Science finds that Theia, the Mars-sized body that collided with early Earth to form the Moon, likely originated in the inner Solar System, closer to the Sun than Earth. 研究人员通过分析月球和陆地岩石中的铁、和同位素,发现地球和月球有几乎相同的化学特征,与内部太阳系的非碳化陨石相匹配。 By analyzing iron, molybdenum, and zirconium isotopes in lunar and terrestrial rocks, researchers discovered that Earth and the Moon share nearly identical chemical signatures, matching non-carbonaceous meteorites from the inner Solar System. 这表明Theia在类似区域形成,解释了组成上的相似性。 This suggests Theia formed in a similar region, explaining the compositional similarity. 研究结果支持了Theia可能在撞击前向外漂移的想法,有助于澄清月球的起源和地球月球系统的早期演变。 The findings support the idea that Theia may have drifted outward before impact, helping clarify the Moon’s origin and the early evolution of the Earth-Moon system.
