i see all these people posting all these questions about english so lets see if some of you brilliant people can answer a few simple ASTRONOMY questions.. Just answer what you can and lets see the various levels of intelect here at FK hehe =]



Here we go....

1) Explain the difference between solar time, sidereal time, and the time kept by atomic clocks.

2) A constellation is a grouping of stars that appears near each other on the sky. Are the stars in a constellation all at the same distance from us? Explain

3) For Each of the Following types of motion, state whether the motion is due entirely to movement of the observed object, due entirely to the Earth's (observer's) motion, and the earth's motion: annual motion of the sun: daily rising and setting of the stars: retrograde motion of a superior planet; and daily rising and setting of the sun. Briefly explain each answer.

4) Why do we have a north pole star, but not a south pole star? Will we always have a north pole star? Explain.

5) Consider the meridian, the imaginary north south line that passes overhead at your lacation. A star crosses it again the next night. Does the start cross the meridian at exactly the same time each night? Explain. Exactly how long is the period between crossings?

6) How would our seasons be different if the Earth's axis were not tilted (that is, if the axis were perpendicular to the Earth's orbital plane)? What would the seasons be like if the Earth's axis were tipped 90 degrees instead of 23.5 degrees?

7) Explain why the moon is never visible on certain nights.

8) Explain why a solar eclipse is often followed by a lunar eclipse about two weeks later.
