UnverifiedUnder China's unified use of Beijing time, spanning roughly five time zones from east to west means the difference between true solar time and civil time can reach one to two hours, enough to change hour boundaries or even day-boundary attribution, thereby affecting the Four Pillars or the Zi Wei life palace.67% similarUnverifiedThe solar irradiance in orbit is approximately 8 times the peak value on the ground, and is unaffected by atmospheric absorption, day-night cycles, or weather, with a theoretical generation duration of up to 24 hours.65% similarUnverifiedThe lunar night lasts about 14 Earth days, and solar power supply will be interrupted for a long time.64% similarUnverifiedSunlight takes about 8 minutes and 20 seconds to reach Earth.63% similarUnverifiedAbove 600 km, even with a drag sail deployed, deorbiting may still take several years during a solar activity minimum.57% similar
