I have found definitions calling it a stony metiorite, calling it a meteor of silicate, a granite meteorite, or even calling it a metallic rock from space and more. What is the actual definition?
An aerolite is, exactly, a dated term from protoscience practitioners. The term has been completely superseded by modern workers, in modern times, using modern data. The term dates back to the time when meteorites- as “rocks from the sky”- were still in doubt by many.
That you still encountered the term “aerolite” in 2023 is a tribute to record preservation and good curation practices, not to the word being useful or relevant in any way to us modern practitioners. You can regard the word as dutifully as you regard rule by nobility, using ships-of-the-line, to fight Barbary pirates. All date to the same period.
