Stars appear to move across the sky each night because the earth is moving, but not the stars. Also some stars are only visible during certain seasons because as the earth rotates, they become visible.
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.
Is the North Star visible in North America only at night during the spring and the summer?
It's only visible at night, but it is visible all year round in North America. In fact, it never goes below the horizon anywhere north of the equator.

How many stars are visible to the naked eye in Delhi?
In Delhi only 50-60 stars are visible just because there is a lot of pollution so the sky is full of dust and also because the Ozone layer protects the Earth with Atmosphere so maximum only 50-60 stars are visible.

Some constellations can be seen only during certain seasons?
Yes, because the sun blocks our view of some stars. as the earth revolves further around the sun (over the course of a year), the stars that were originally blocked become visible from earth and stars that were once visible are now hiding on the other side of the sun. there are also stars that you will never be able to see without travelling to the southern hemisphere of the earth.

Why are titanium oxide features visible in the spectra of only the coolest stars?
Stars with titanium oxide only visible in cool burning stars because their structures, molecules can absorb photons at many wave lengths , producing numerous, closely spaced spectral lines that blend together to form bands. These bands form only in the coolest stars, this is because the molecules are not subjected to violent collisions.
Are smaller stars closer to earth?
No, but because small stars emit less light than large ones, they are only visible to the naked eye at comparatively "short" distances in interstellar terms while larger, brighter stars are visible at much greater distances.
Is polaris visible from all places on earth?
