Cosmonium supports the following navigation mode :

• Free flight
• Follow body
• Synchronous orbit
• Body tracking

Cosmonium can show the following annotations on the displayed bodies :

• Orbit
• Rotation axis
• Reference frame

It also supports the following grids and guides :

• Constellation and constellation boundaries
• Constellation asterisms
• Equatorial grid
• Ecliptic grid

Cosmonium only supports keplerian orbits and uniform rotations. Support for more precise orbits and rotations will be added later.
