Astrolaxy
A Go library for astronomy, physics and mathematics
Key features
-
Lightweight, fast and simple: astrolaxy is extremely fast and lightweight, and was built only with built-in libraries. The Go language is much faster than Python, and just as easy, and using astrolaxy, calculations in physics, astronomy, mathematics, and science in general are perfect;
-
Efficient and precise: All formulas are original and tested, they are perfect;
-
More than 50 formulas: It's a big toolbox! It has everything you need;
-
Open-source: Anyone can use and modify astrolaxy, it's open-source;
How to install
You can install it with go get, see:
go get -u github.com/simplyYan/astrolaxy-go
Docs
The library is very simple to use and you can access the documentation via pkg.dev:
