how many stars are visible to the naked eye in the northern hemisphere?

Answer 1

too many to count, unless your stoned......

Answer 2

That depends on where in the northern hemisphere you are standing.

In downtown NYC or LA, you probably can't see any stars at all because of all the light pollution.

In the desert, say, in northern Arizona, thousands.

One estimate has the number of naked-eye visible stars in the northern hemisphere at ~4000:

Another estimate puts it at about 5000. A third puts it at 2000.

Take your pick.

Answer 3

The cut back of visibility for the human eye is oftentimes taken to be importance 6.0, whether this is far less for those with detrimental imaginitive and prescient, and a sprint extra useful for those with dazzling imaginitive and prescient. yet provided that fee, and after combining double stars, there are a finished of 5034 stars interior the celestial sphere of magazine 6.00 or brighter, in accordance to the Yale bright megastar Catalog. (There are 9096 entries interior the finished catalog, yet lots of those are dimmer than 6.00, and a brilliant style of incorporate doubles.) provided that a pair of million/2 are under the horizon at all people time, that could go away approximately 2517 stars above the horizon, at magazine. 6.0 or brighter -- IF the Earth had no environment. yet of course it rather is not the case. in actuality, the Earth's environment absorbs some easy no rely how clean this is. If we expect the actually appropriate case -- 0 aerosols, meaning no airborne dirt and dust, no vapor, no cloud droplets in any respect -- the relax environment nevertheless absorbs approximately 0.13 magnitudes according to airmass. once you look on the instant up, you're looking by way of a million airmass; at an altitiude of 30°, you're looking by way of 2 airmasses; and perfect on the horizon, you're looking by way of approximately 38 airmasses. So at a minimum, after accounting for atmospheric extinction, you will desire to easily see a megastar with a pre-extinction importance of 5.87 or brighter interior the appropriate case (on the zenith). That takes us all the way down to 4398 stars interior the celestial sphere perfect there. And maximum stars are no longer on the zenith; the final megastar is seen by way of 2 airmasses, which might enable purely stars with magnitudes of 5.seventy 4 or brighter to be seen. That takes us all the way down to 3763 stars interior the celestial sphere. of those, a pair of million/2 would be under the horizon, so the terrific answer is: variety of 1881 stars seen with the bare eye at all people time, below appropriate circumstances. thank you for a fascinating question. Starred.

Answer 4

The dimmest star visible to the naked eye is at about magnitude 6.0. There are about 6000 such stars in the whole sky. But some of those stars are permanently below your horizon from most latitudes. The number you could actually see depends on your exact latitude; it would vary from about 3000 (at the north pole) to all 6000 (on the equator).

Answer 5

more then 1.

Answer 6

In a clear night all around the horizon...naked eye someone can count no more than 10.000 stars.

Answer 7

how many hair is on ur left side of the head, that's the exact number

Answer 8

around 1000.

If you are on a mountain probably it gets closer to 10.000.

Answer 9

from zero (with total cloud cover) to a lot (with no cloud cover)

Answer 10

lots and lots and lots ....need i say more .....but boy they sure are fun to look at !!!
