Tonight from Tehran

Tonight in Tehran, Iran, the sun sets at 19:03 local time and astronomical darkness — when even the faintest stars become visible — arrives at 20:39. The moon is in last quarter phase, 36% illuminated. 5 major planets are above the horizon as night falls. Sunrise comes at 05:17.

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.
