Infinite and Unknown.
But I think the point is "night sky" meaning, OUR night sky, or our visual field here on Earth. It's not a question of how many stars are in the universe. The answer depends on your location and the brightness of ambient terrestrial lights but can be as many as 13,000.

The OBSERVABLE UNIVERSE has roughly 1011 galaxies, and a galaxy typically has 1011 stars; for a total of about 1022 stars. If you write it out, that's a 1, followed by 22 zeros.
cw: It was once argued that there couldn't be an infinite number of stars because the sky would be a blanket of white. That argument was before space dust, gravity, etc. were known to affect the transmission of light in the Cosmos. The key word, of course, as Dr. Zonneveld has said, is Observable.

Spectrum indicates what in the stars atmosphere?
The chemical composition of the star atmosphere.
Are there stars in the stratosphere and are there stars in the mesosphere and are there stars in the thrmosphere?
yes, there are aproximately over 9000 stars in each layer of the atmosphere
Why cant you live on stars?
Stars are way to hot to live on. They also have on atmosphere
How does the lack of atmosphere affect the temperatures on mercury?
Mercury has the thinnest atmosphere so the fast winds from blown up stars go to the thin atmosphere, it will be easier to get in and change the atmosphere
Does any shooting stars go by mercury?
Shooting stars are all in our atmosphere, they are meteors.
Can stars fall from the atmosphere?
No. The stars are well beyond the atmosphere and are not influence by Earth at all. The stars may look small in the sky but they are enormous, far larger than Earth and unimaginably far away.
Why do stars come out?

What layer of atmosphere has stars?
