astroterm

A terminal-based star map. More information: https://github.com/da-luce/astroterm#usage.

• Display real-time positions of stars and planets based on your current location:

astroterm

• Display constellations, use colour, and render the simulation at the given frame rate:

astroterm {{[-C|--constellations]}} {{[-c|--color]}} {{[-f|--fps]}} {{60}}

• Use unicode characters instead of the basic ASCII characters, and only render stars brighter than the given magnitude:

astroterm {{[-u|--unicode]}} {{[-t|--threshold]}} {{2.0}}

• Use a given latitude, longitude and datetime:

astroterm {{[-a|--latitude]}} {{90.0}} {{[-o|--longitude]}} {{-180.0}} {{[-d|--datetime]}} {{2025-08-04T12:00:00}}

• Use the longitude and latitude of a given city, and set the speed of the simulation to a given factor:

astroterm {{[-i|--city]}} {{Singapore}} {{[-s|--speed]}} {{1000.0}}
