If Polaris cannot be seen because it is just a little below the horizon then you must be located?

Where in the sky is the north star when viewed from the equator?
It is not visible at or south of the Equator. Theoretically , it would appear on the horizon. Remember the Pole Star is overhead at 90 degree N. (The North Pole). So when you have reached the Equator, your angle has changed by 90 degrees because you are now at 0(zero) degrees. So viewing the sky Polaris (Pole Star) will has now changed its angle by 90 degrees. So from being overhead, a 90 degree angle will be the horizon. You don't see Polaris at the Equator, because of the density of the atmosphere, dust and dirt and moisture in the atmosphere.
Why the event horizon of a black hole stop the light from getting rid of that?
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.
Can the north start be used to calculate latitude?
Yes, the North Star (Polaris) can be used to calculate latitude in the northern hemisphere. By measuring the angle between the horizon and the North Star, you can determine your latitude. The angle is equal to your latitude.
What is the name for the boundary around a black hole beyond which events cannot affect the observer?
The boundary around a black hole beyond which events cannot affect an outside observer is called the event horizon. Once an object crosses the event horizon, it is impossible for any information or signals to reach an outside observer due to the extreme gravitational pull of the black hole.
What can be detected from matter that has crossed an event horizon?
Once matter crosses an event horizon, it cannot escape. Therefore, no information or signal can be detected from the matter beyond the event horizon. This is due to the intense gravitational pull of the black hole that prevents anything, including light, from escaping.
Why an observer in the southern hemisphere cannot see the star polaris?
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.
Why is polaris the brightest star?
The question cannot be answered because it is based on a false premise that Polaris is the brightest star.

What planet has a event horizon?
No planet has an event horizon. A black hole has an event horizon; it is the radius within which light cannot escape.

How is the curved horizon proof of the Earth shape?
we have a horizon which means that we cannot see all of the earths surface
Can the north start be used to calculate latitude?
Yes, the North Star (Polaris) can be used to calculate latitude in the northern hemisphere. By measuring the angle between the horizon and the North Star, you can determine your latitude. The angle is equal to your latitude.
Can you see Polaris from any point on earth?
No, Polaris can only be seen in the Northern Hemisphere. It is not visible from the Southern Hemisphere.
Why is Peru located where it is?
You cannot answer such a question. It's located where it is simply because that's its placement.
Exactly vertical or perpendicular?
There is no such thing as exactly vertical because either it is vertical or it is not. You cannot have approximately vertical - it is not vertical, then. Vertical means at 90 degrees to the horizon (or horizontal).
Can you see the north star from the southern hemisphere?
No, the North Star (Polaris) is only visible in the Northern Hemisphere, and cannot be seen from the Southern Hemisphere. Instead, the Southern Hemisphere has its own celestial pole, which is marked by the Southern Cross constellation.
Can polaris only be seen in the Northern Hemisphere while winter?
On any night of the year, Polaris can be seen from the northern hemisphere and cannot be seen from the southern one. (Assuming the sky is clear in the north.)
