ASTR 1210 (O'Connell) PUZZLAH PREP QUESTIONS
PUZZLAH PREP: LECTURE 3
These puzzlah-prep questions relate to topics that might form
the basis of in-class puzzlah questions for a given lecture.
Consider them while reading over the Study Guide and reading
assignment.
The topics are not guaranteed to be included as puzzlahs, nor
would a puzzlah necessarily be formulated as are the questions
here.
If the universe is spatially infinite, as stated in Guide2,
how many planets like the Earth is it likely to contain?
If the stars seen overhead from a given location move in the sky
from east to west during the night, in which direction does the Sun
move during the day?
True or false? Stars near Polaris, the ''north pole star'', never
rise or set. Instead, they appear to move around Polaris in a counter-clockwise
motion.
True or false? "Constellations" are physical groups of stars that
lie near one another in 3-dimensional space.
