How many satellites and how much debris does Taiwan have in orbit?
Numbers last changed (orbit data of , catalogue of ). CelesTrak's catalogue records 35 objects in Earth orbit for Taiwan: 27 active satellites, 8 inactive satellites, 0 rocket bodies and 0 pieces of debris.
What this means
The catalogue records these objects under the owner "Taiwan (Republic of China)" (code ROC). That ranks 22nd of 106 owners, after Australia (43) and ahead of Sea Launch (34). No debris in Earth orbit is recorded under this owner.
The 2-hourly orbit data agrees: 27 active.
