31. Taiyuan Satellite Launch Center is located in Shanxi province and focuses on the launches of Sun-synchronous orbit satellites. 32. Metis lies inside Jupiter's synchronous orbit radius ( as does tidal forces slowly cause its orbit to decay. 33. Take a look at sun-synchronous orbit . 34. On 18 December, the Ariane 5GS made its final flight, delivering the Helios-IIB satellite into a sun-synchronous orbit . 35. In October 2012, Virgin announced that LauncherOne would be designed so that it could place in Sun-synchronous orbit . 36. For Earth, a semi-synchronous orbit is considered a medium Earth orbit, with a period of just under 12 hours. 37. Most are in sun-synchronous orbits . 38. Orbital decay can occur due to tidal forces for objects below the synchronous orbit for the body they're orbiting. 39. A semi-synchronous orbit has an orbital period of ?sidereal day, i . e ., 11 h 58 min. 40. Since the Thalassian orbit is below Neptune's synchronous orbit radius, it is slowly spiralling inward due to Despina's orbit.
