## What is Asteria?

Asteria - Star Map & Live Satellite Tracker by the makers of ISS Detector

Track the August 28th partial Lunar Eclipse!

Point your phone at the night sky and explore the cosmos in real time with Asteria! Whether you’re a casual stargazing enthusiast, an amateur astronomer, or a satellite tracker, Asteria brings a complete AR sky map directly to your screen.

Using your device's GPS, compass, and gyroscope, Asteria aligns a stunning 3D star map with your view, showing you exactly what is above you. Day or night.

(Note: Basic sky tracking, stars, planets, and space stations are free. Tracking advanced categories like Starlink satellite trains, bright satellites, comets, and meteor showers requires a Premium subscription.)
