一项陨石研究表明早期太阳系呈甜甜圈形状，这对之前的飞镖状同心环理论提出了挑战。 A meteorite study suggests the early solar system was donut-shaped, challenging the previous dartboard-like concentric rings theory. 铁陨石揭示了我们太阳系的原行星盘呈甜甜圈形状，难熔金属向外移动并被木星捕获在外太阳系中。 Iron meteorites reveal that the protoplanetary disk of our solar system was doughnut-shaped, with refractory metals moving outward and trapped in the outer solar system by Jupiter. 我们对太阳系形成的新认识为其早期历史提供了新的视角。 This new understanding of our solar system's formation provides a fresh perspective on its early history.
