This doomed alien planet has a year that lasts just 16 hours — it’s only getting faster

The newly announced exoplanet belongs to a category scientists refer to as “hot Jupiters.” These worlds are built more or less like our solar system’s behemoth, but orbit much closer to their stars, hence the nickname. Although astronomers have identified more than 400 hot Jupiters to date, researchers say none are quite like the new discovery, which is designated TOI-2109b.
