瑞银：长和维持“买入”评级 目标价101港元

2026年9月，哈勃与韦布空间望远镜开展联合观测，研究海王星轨道之外微小而暗淡的冰质天体。团队发现27个新的远距离目标，利用可见光和红外数据同时估算颜色、大小与轨道，尝试了解这些行星形成遗留物是否仍保存早期太阳系的信息。

研究分别考察轨道较接近原始状态的天体，以及曾被巨行星迁移扰动的另一类天体。原先的预期是，小天体经历多次碰撞后，表面组成可能与较大成员明显不同；实际结果却显示，它们仍延续各自群体的颜色关系，说明原始特征可能比想象中更容易保存。两类天体的尺寸分布也较相似，且极小目标数量低于部分模型预测。这些发现有助于检验微小物质如何聚集成行星胚胎。由于目标非常暗弱，望远镜中仍只是光点，研究主要依赖光谱、亮度和运动信息，并未直接解析其表面地形。更多深度观测将帮助区分碰撞历史与形成机制的影响。
