1983 年——发现“岩石彗星”Phaethon，即双子座流星雨的来源，在没有明显尘埃释放的情况下释放气体，促使日本的 Destiny+ 任务进行研究。 1983-discovered "rock comet" Phaethon, source of the Geminid meteor shower, emits gas without significant dust release, prompting research by Japan's Destiny+ mission.

Phaethon,1983年发现的一颗“岩石彗星”,是Geminid流星雨的来源。 Phaethon, a "rock comet" discovered in 1983, is the source of the Geminid meteor shower. 独特的是,当太阳加热时,它释放气体时没有大量尘埃释放,引起对其构成的疑问。 Uniquely, it emits gas without significant dust release when heated by the Sun, raising questions about its composition. 最近的研究表明,硫化铁矿物分解成二氧化硫等气体,在表层下积累。 Recent research suggests that iron sulfide minerals break down into gases like sulfur dioxide, which accumulate beneath its surface. 日本航天局即将进行的 Destiny+ 任务将探索这种行为，该任务旨在增强对 Phaethon 特性的理解。 This behavior will be explored by the Japanese Space Agency's upcoming Destiny+ mission, aimed at enhancing understanding of Phaethon's characteristics.
