Stars Tonight in Rio Grande, Tierra del Fuego, Argentina

Making the most of the night sky from Rio Grande, Tierra del Fuego, Argentina

Stars do not move relative to each other, but the whole sky turns as Earth rotates and shifts through the year as Earth orbits the Sun. That is why the brightest stars listed here change from month to month, and why a star that is overhead at 9 pm in winter is gone by summer. The positions above are worked out from your latitude and the time, so they hold for Rio Grande, Tierra del Fuego, Argentina specifically.

Give your eyes 20 minutes. Dark adaptation takes about that long, and a single glance at a phone screen resets it. Use a red light if you need to read a chart. Away from streetlights and with no Moon, you can see several thousand stars; under city lights, a few hundred.
