Show HN: StellarSnap – Explore NASA APODs, simulate orbits, learn astronomy

21 points by stellarsnap 3 days ago

I built StellarSnap as a calm, ad-free space to explore NASA’s Astronomy Picture of the Day (APOD) and learn astronomy along the way.

What it includes:

- A clean APOD archive browser with a Random APOD button

- A growing Glossary with term highlighting across the site

- A 2D Orbit Simulator where you can test satellite motion with real physics

- A deeper Encyclopedia, still early, but expanding

- Subtle touches like “see past APODs using this term”

- And more to come

It’s entirely ad-free, cookie-free, and not affiliated with NASA, but I was honored to have StellarSnap mentioned on the official APOD About page by Professor Robert Nemiroff: https://apod.nasa.gov/apod/lib/about_apod.html

Always open to ideas, critiques, or ways to make it better.
