The Hubbel telescope has recently spotted a strange asteroid with six comet-like tales. Whenever I hear interesting scientific news like this I always want to know if (and when) science fiction authors first wrote about such an event.
Turns out in 1835, Sir Thomas Charles Morgan (1783-1843)--husband of the popular novelist Lady Morgan--came pretty close. He wrote the first science fiction short story where the protagonist rides on a comet that he controls by a "filial or two" of concentrated gravity. The tale is called "Glimpses of Other Worlds" and you can find it my recently published anthology - Mesaerion: The Best Science Fiction Stories 1800-1849.
