太阳系九大行星中,木星、土星、天王星、海王星等大行星周围都有规模不等的光环。据分析,这些光环基本上都是由冰物质凝结而成的。但是,离太阳较近的水星、金星、火星都没有光环。那么,人类赖以生存的地球周围有没有光环呢? 有些科学家认为,地球和其他大行星一样,同在太阳系中绕 Among the nine planets in the solar system, there are rings of varying sizes around the planets such as Jupiter, Saturn, Uranus, and Neptune. According to analysis, these auras are basically made of condensed ice materials. However, Mercury, Venus, and Mars that are closer to the Sun have no aura. Well, there are no halos around the earth on which human beings live. Some scientists believe that the Earth, like other large planets, is also wound up in the solar system.
