I really like Stellarium and SkySafari but I felt like these are primarily geared towards exploring the sky but not so much "here are the long list of things I want to see, when can I see them tonight and where". There's also not really a great option I've found that combines sky object planning + location weather details while still being free so I built this. The UI's heavily inspired by NINAs sky atlas + Robinhood. Right now you can: View the altitude chart of objects and 3D view Create lists of objects of interest View the annual max/min daily altitude of an object to find the best…

Hey HN! I made Orbit, an iOS app that allows you to see the satellites, planets, and constellations above you in AR, on a 2D map, and on a 3D globe. The app includes more than 15,000 objects tracked by CelesTrack, together with their pass predictions, descriptions, and detailed orbital data. A searchable catalog of all objects is also available, as well as a built-in chatbot designed to answer any space-related questions you might have. This is my first published iOS app, so any feedback is greatly appreciated! App Store: https://apps.apple.com/app/id6772174570

I don't always all-caps, but when I do, it's because every word is an acronym. The NASA HORIZONS[1] system is a telnet service that provides planetary data and ephemeris tables, which are basically coordinate-time plots for celestial bodies. It's pretty archaic and somewhat difficult to use, especially since it just dumps out text tables and you have to parse it to do anything with it. Some projects, e.g. KDE Marble, use it as a data source and typically just consume it with a little procedural code to get what they need. I wanted to provide a full-fledged library for it so that you can…

Hello HN! My name is Rémy and I recently published an astronomy dashboard where everything is open source: the code of the website, the framework it is based on and the library that computes astronomical data. For the last few years, I have been developing the Ruby library Astronoby (https://github.com/rhannequin/astronoby) with as much dedication and perseverance I could while I don't have any scientific academic background. My end goal was to use this library and build a website that not only provides as much data as possible, but let anyone access and understand how it…
