About Tiangong
Tiangong (meaning "Heavenly Palace") is China's modular space station, operated by the China Manned Space Agency (CMSA). The station was completed in late 2022 with the addition of the Mengtian laboratory module, joining the core Tianhe module and the Wentian laboratory module.
Tiangong orbits at a slightly lower altitude and inclination than the ISS, which means it passes over different parts of the Earth. It is the second-brightest space station visible from the ground, reaching magnitude –2 or brighter on good passes.
How to Track Tiangong
Open the Orbital Radar live tracker and use the Stations panel to highlight Tiangong. The station is tracked in real time alongside the ISS and all other objects in the catalogue.
Visibility
Tiangong is visible to the naked eye under the same conditions as the ISS — in the hours after sunset and before sunrise. It appears as a bright, steady moving light. Use the Sat Pass tool to check when it passes over your location.
