Periapsis opens on a live global view. Move around first, then use the controls at the edge of the scene to investigate a target.
Drag to move the current view and scroll to zoom.
Drag with one finger to move the view, pinch to zoom, and use the controls without leaving the scene.

This is the satellite menu. After the tour, choose Satellites and search by name or catalogue number.
Selecting a result adds its orbit and card; use its Focus control when you want to follow it.

This is the layout control. After the tour, it switches between the globe and map views so you can use whichever makes a pass easiest to read.
On a wide desktop display, it can also place the two views side by side.
On a phone, globe and map switch one at a time; split views are desktop-only.
Upper-right layout control

Enjoy the orbit.
