Asteroid Radar is an app to view the asteroids detected by NASA that pass near Earth, you can view all the detected asteroids given a period of time with data such as the size, velocity, distance to earth and if they are potentially hazardous.
The project follows a single activity, and Model-View-ViewModel architecture.
The app consists of two fragments:
- MainFragment: shows the list of asteroids (can be sorted by today/weeks/hazardous filters)
- DetailFragment: shows detail of an asteroid instance when clicked from the MainFragment

- MVVM architecture
- Coil library to display images dynamically
- WorkManager API - to download data in the background once every 24 hours
