The number of requests is limited unless you sign up for X-App-Token (which you can do for free).

Acceptance criteria:

● We would like the meteors to be filtered from the year 1900.
● If a user selects a meteor, a map should be presented with a pin that indicates the
location of the fallen meteor. You can include any other details that might be interesting (size, date, etc.).
● Users should be able to manage favourite meteors: add a new meteor to their favourites
and remove meteor from the list. It’s up to you how you want to manage this: using persistent local storage or using some (out of the box) backend solution.
● Users should be able to change the sorting of the meteor list to size, location, etc. (any other sorting that you feel is relevant).
● The data should be fetched on app launch and the user should have a way to refresh the data while using the app.
● Design and UI of the app is completely up to you, but try to keep it simple and clean.
