Night sky over Beijing
The page stands in Beijing (39.9° N, 116.4° E) and looks up at tonight's sky over it: by day its clock starts at Beijing's dusk, so the Moon, the planets and the bright stars are where they will be once it's dark there, with the satellites in sunlight crossing between them.
The list below says tonight over Beijing in words, worked out as the page is served: sunset and when it gets dark on Beijing's clock (Asia/Shanghai), the Moon's phase and when it's up, and for each planet when it rises or sets, how high it climbs and where to face, with the next meteor shower.

How to read it
Beijing, at 39.9° north, has a dry, continental climate: autumn and winter bring cold, clear air from the northwest, which leaves crisp skies once it has swept away the haze, while the summer monsoon brings most of the year’s rain in July and August. The city’s air has cleared markedly over the last decade, and so has its night sky.
The Ancient Observatory on the old city wall kept its bronze instruments trained on the sky from the Ming dynasty on, and the Beijing Planetarium opened in 1957. About 120 km northeast, in the hills of Hebei, the Xinglong Station of the National Astronomical Observatories houses the LAMOST survey telescope, under far darker skies.
Questions
Where can you see the stars near Beijing?
North and northeast of the city, in the mountains of Miyun, Huairou and Yanqing, where the Great Wall runs along the ridges: an hour or two’s drive puts the city’s glow behind the hills. Within the city, the Moon and planets are visible from any open space.
When is the night sky clearest in Beijing?
September to November, and windy days in winter when a cold front clears the air; still winter days can trap haze. July and August are the rainy season, with frequent cloud and thunderstorms in the evenings.
