If Polaris cannot be seen because it is just below the horizon, you must be located at a latitude slightly south of the North Star's position, which is approximately 90 degrees north. Specifically, you would be at a latitude of about 89 degrees south or lower, as Polaris is only visible in the Northern Hemisphere. In this situation, you would be too far south to see Polaris above the horizon.
For an observer standing on the equator, the North Star Polaris is not visible. If it were, it would be right on the northern horizon, but from the equator, it is probably hidden behind a tree or in the sea mist.
An observer would not see Polaris, also known as the North Star, in the night sky at any time during the year if they are located south of the equator. This is because Polaris is positioned nearly directly above the North Pole, making it visible only in the Northern Hemisphere. As one travels further south, Polaris gradually sinks lower in the sky until it is no longer visible. Countries such as Brazil, Australia, and South Africa are examples where Polaris cannot be observed.
The event horizon is the point of no return around a black hole where the escape velocity exceeds the speed of light. Light cannot escape from beyond the event horizon because the gravitational pull is so strong that even light cannot overcome it. This is why the event horizon appears to "trap" light within the black hole.
The angle between the horizon and the north star is roughly equal to the observer's North latitude ... always within about 2/3 of a degree. This only works for locations north of the equator. The north star isn't visible at all from places south of the equator.
The "boundary" you're probably thinking of is called the event horizon. Past this point, the escape velocity of the black hole exceeds the speed of light, meaning nothing, including light, can escape it.
Polaris, or the North Star, is located nearly directly above the North Pole, so it is not visible from Cape Town, which is situated in the Southern Hemisphere. As a result, Polaris is below the horizon in Cape Town and cannot be observed from that location.
Polaris, the North Star, is located near the North Celestial Pole which is visible only from the Northern Hemisphere. In the Southern Hemisphere, there is no bright star close to the South Celestial Pole like Polaris because the South Celestial Pole does not have a similarly positioned bright star. Therefore, observers in the Southern Hemisphere cannot see Polaris due to its location in the sky.
The question cannot be answered because it is based on a false premise that Polaris is the brightest star.
For an observer standing on the equator, the North Star Polaris is not visible. If it were, it would be right on the northern horizon, but from the equator, it is probably hidden behind a tree or in the sea mist.

No planet has an event horizon. A black hole has an event horizon; it is the radius within which light cannot escape.
The event horizon is the point of no return around a black hole where the escape velocity exceeds the speed of light. Light cannot escape from beyond the event horizon because the gravitational pull is so strong that even light cannot overcome it. This is why the event horizon appears to "trap" light within the black hole.
we have a horizon which means that we cannot see all of the earths surface
No, "horizon" is not an abstract noun. Abstract nouns refer to concepts, qualities, or ideas that cannot be perceived by the five senses. "Horizon" is a concrete noun because it refers to the line where the Earth's surface seems to meet the sky, which is a physical and observable phenomenon.
The angle between the horizon and the north star is roughly equal to the observer's North latitude ... always within about 2/3 of a degree. This only works for locations north of the equator. The north star isn't visible at all from places south of the equator.
You cannot answer such a question. It's located where it is simply because that's its placement.
No. Polaris cannot be seen at any point (0.5 degrees) south of the equator.
