That's terrible, the only planetary landings I have are 400KLy away and my orbis, which I could not manully place because it was the primary station, is nowhere near them.
Show a map. Mine looks like this:
Built a Refinery hub on the moon. Am now waiting for this "Remove construction" button to remove the scientific surface port being built on the moon. Have one additional slot around the same body as the Orbis and will stop doing any further buildup until the situation with influencing economies will become clearer. Have 3 slots around the main star and will build a Coriolis there, and hopefully switch that one to High Tech with 2 hightech satellites.
Edit: We also do not know so far whether there are
- system wide economy influences
- different necessary economy influences for different colony types, which are
- Tier 1 Outposts (commercial, civilian, criminal)
- Tier 1 planetary ports (civilian)
- Tier 2 stations (Coriolis)
- Tier 3 stations (Orbis, Ocellus)
- Tier 3 starport
- any distance factor
- whether economy is fluid or fixed once defined
- whether the stats of the system (Standard of Living, Wealth, Development) play any role.
Edit2: Here are two examples for systems that managed to switch their economy state with a Coriolis:

Edit3: As assumed, they have Coriolis + settlements + installations all around the same body (assumed by the same distance from the star)
