Title: How many stars in the most dark sky without {The_Sun-0001} naked eye with 20/20!
Post by: remotemass on 24/01/2024 11:14:42
Hello,

I am a computer scientist from London South Bank University.
(I am working on some interesting projects, namely an improvement of the Sun-Dial-Clock, casting both the Sun and the Moon with 24/7 neon/like RED-BLUE handles, the 24h cycle and the 27-29 days cycle. We think the DIAL shall be a vertical bar cylinder with 11.11 centimetres of diameter and that at the top we shall have a WHITE LIGHT BRIGHT torch with diameter 11.11 centimetres pointing to the centre of the smallest circle that can contain all the point-stars of ORION constellation that is well signed to our future bionic race, the ancestral Aryan-Zion Race of the past).

I need an answer from NASA and the European Space Agency (ESA) to this question:

"In a VR environment that emulates the number of visible stars for a quite average human naked eye with 20/20 vision, how many stars are visible? Assume the light of the sun, Star_0001 can all be suppressed and that the light from our planet, Earth, and its natural satellite, the Moon, can also be supressed in the VR sky."

If possible provide a list of all those stars, starting with the Sun: 0001-xxxx_

Explain all of your rationale and provide sources. How many stars can be seen, dark sky, naked eye, average human vision 20/20.

Then why are you asking us?

Why not just ask google or wiki?
https://en.wikipedia.org/wiki/List_of_brightest_natural_objects_in_the_sky

There are thousands of visible stars.
You can find a list here.

This is not nasa or the esa.

Further more it is a" how long is a piece of string" question

An answer I recall from long ago was around 7,000 stars brighter than magnitude 6.
- Looking on the internet, I see answers between 2,000 and 10,000 (the latter if you were to roam to both hemispheres).

Neil deGrasse Tyson grew up in the canyons of New York CIty, and tells of the time he first went to the Haydn planetarium.
- When they threw up an image of thousands of stars, he thought it was a joke. He had only seen about 4 at a time...
- He is now director of the Haydn planetarium
