During the daytime, all of it; at night, no part of the Sun. During a short time, during sunrise, only part of the Sun is over the horizon.Note: This is for a specific observer; you can always find a point on the Earth where the Sun is above your head.
No. The pattern made by a group of stars doesn't change, although its place and orientationin the sky depend on the observer's location, the time of night, and the time of year.
The altitude doesn't depend much on whether the night is clear.If you live in the northern hemisphere, the altitude of Polaris above the horizon will APPROXIMATELY be equal to your latitude. If you live in the southern hemisphere, Polaris will be BELOW the horizon, as many degrees as you are south of the equator.
That person in London would see a new moon.
Near the equator.
Each night, the altitude decreases in the northern sky.
Why does Polaris not seem to move during the night? 1 point BECAUSE IT IS LOCATED NEAR THE NORTH POLE BECAUSE IT IS FIXED IN THE SKY BECAUSE URSA MINOR DOES NOT MOVE BECAUSE IT REVOLVES AROUND THE SUN WITH EARTH
Polaris, which is located at directly North.
It's an illusion caused by Polaris being (almost) in line with the Earth's axis of rotation.
Polaris, or the North Star, was one of the brightest stars in the Northern Hemisphere and has a relatively stable close polar orbit. As such, it always points north and is thus a reliable guide at night.
No. The brightest star in the night sky is Sirius.
Because it is in line with Earth's axis of rotation, Polaris never rises or sets. It is always in the same place in the sky from any given location in the northern hemisphere.

Polaris, the North Star, would only appear overhead if you were standing at the North Pole. From my location near Sacramento, CA, the star Polaris is visible about 40 degrees above the horizon, and is always in the same place. It does not appear to move.
