How to add Eris and other Trans-Neptunian Objects

Want to include Eris, Makemake, or Haumea in your charts? You can easily turn them on in your chart settings.

Here’s how to do it in the TimePassages mobile app:

1. Go to the Settings tab (bottom right).

2. Tap Default Chart Settings.

3. Scroll down to the Chart Points section.

4. Look for the toggles for Eris, Makemake, and Haumea—and switch them on (green means they’re active).

That’s it! These chart points will now appear in any new charts you create.

Need to apply this to an existing chart instead? Check out How to Change My Chart Settings, or you can quickly contact our support team directly from the app:

1. Tap Settings (gear icon in the bottom toolbar).
2. Tap Report an Issue at the bottom of the page.
3. Fill out the support form with a short description of the issue.
