Asteroid 2.3 times the size of dinosaur heading for Earth - NASA
How many Olympic Swimming Pools is that?
An Olympic swimming pool has a defined size, so that is a meaningful, if unorthodox, means of comparison; the term "dinosaur" by itself, does not, because dinosaurs came is so many different sizes, from the tiny microraptor, to the behemoth titanosaur. An asteroid that was 2.3 times the size of a microraptor would leave some pretty colors in the night sky, and that would be about it; an asteroid 2.3 times the size of a titanosaur, for example, the Patagotitan, would leave a serious crater and devastating consequences.
