According to SIMBAD, ~970. But there's a lot of stars within 50 light years whose distances aren't known. There's quite a few stars within 50 light years. To get a good estimate, we should consider how many stars within 20 light years, and go from there.
The nearest 25 light years are really well catalogued, and the current census is 200 stars. Now, through knowledge of Geometry, one can say that if you multiply the radius of a 3D shape by a number, x, the volume will increase by the x^3. Why 3? because it's a 3D shape.
So we double our sphere from 25 to 50 light years. So thus the volume increases by 2^3 = 8 times! So there are 8 times as many stars within 50 light years as there are within 25 light years.
200 * 8 =
1,600 stars (estimate).

How many stars are located within 1,000 light years from Earth?
Ah, what a fascinating question! I don't have an exact number of stars within 1,000 light years from Earth, my friend, but just imagine the beauty and wonder of each one. The vastness of our universe holds countless stars, each shining brightly and adding their own special touch to the night sky.
What are some of the nearest stars to earth?
Some of the nearest stars to Earth include Proxima Centauri, Alpha Centauri A and B, Barnard's Star, and Wolf 359. These stars are all within a few light years of our solar system.
How many light years away in Orion?
The Orion constellation is approximately 1,344 light-years away from Earth. This distance can vary slightly depending on the specific stars or objects within Orion that are being measured.
Are the hottest stars the red stars?
Red stars are the coolest. They are usually between 3,000-6,000 degrees Fahrenheit. They include Proxima Centauri (4.2 light-years from Earth) and Betelgeuse (350-650 light-years from Earth). The cooler and smaller the star, the longer it lives. Blue stars are the hottest, but the LBV types, such as Eta Carinae (7,500 light-years from Earth) and R136a1 (163,000 light-years from Earth) are the hottest and heaviest in the universe. They could range temperatures from 50,000-100,000 degrees Fahrenheit.
How far puppis from the earth?
Puppis is a constellation located in the southern sky. The distance between Earth and the stars in the Puppis constellation varies greatly, as different stars within the constellation are located at varying distances from our planet. Some stars in Puppis may be tens to hundreds of light-years away from Earth.
Do All stars in a constellation have to be within a light year?
No. No star other than the sun is within a light year of Earth. Most of the stars in constellations are dozens to hundreds of light years away.
Is the distance between stars and earth measured in kilometres or light-years?
Light Years.
Does it sometimes take millions of years for starlight to reach earth?
Not for the stars you can see without a telescope. All of the stars you see at night are within a few hundred light years of Earth, so it does not take the light more than a few hundred years to reach us. There are stars in other galaxies that are millions or even billions of light years away. That light does take millions to billions of years to reach us, though the stars are too far away for us to thee them individually.
How many years does starlight travel?
It depends on the distance of the star to Earth. The distance to the star in light years is the number of years the light took to get here. Most of the stars we see at night are within a few hundred light years of Earth. The closest star other than the sun is about 4.2 light years away.
In astronomy when said stars are close together as in constellations how far in light years are they distanced from one another?
Could be any distance. Generally, however, the bright stars that are part of constellations are within a few hundred light years of Earth.
