Tonight from Seoul

Tonight in Seoul, South Korea, the sun sets at 19:57 local time and astronomical darkness — when even the faintest stars become visible — arrives at 21:51. The moon is in first quarter phase, 56% illuminated. 3 major planets are above the horizon as night falls. Sunrise comes at 05:11.

At mid-latitudes, night length varies substantially with season; summer offers shorter darkness, winter the longest. Polaris sits roughly at this latitude above the northern horizon, making it a permanent compass for navigation. The Big Dipper, Cassiopeia, and the northern circumpolar stars never set.
