astroterm

astroterm is a terminal‑based star map written in C that renders the night sky as ASCII graphics. It shows the real‑time positions of stars, planets, constellations, the Moon and its phases, allowing users to specify any date, time, and geographic location to view past, present, or future celestial configurations.

The tool targets developers and hobbyists who work in command‑line environments and want a lightweight way to explore astronomical data without graphical interfaces. It offers precise, terminal‑friendly visualizations of celestial objects and supports customizable sky views through command‑line options.

Distinctive aspects include its performance‑optimized rendering, which keeps the program fast and low‑resource, and its availability as a prebuilt executable and through multiple package managers such as Arch Linux, Fedora, Homebrew, Nix, and Guix. The project is stable, MIT‑licensed, and welcomes contributions via its repository.
