LT's (position)
it does not rise or set
at which position(s) if any, does star B rise and set?
No (the earth is blocking it)
can the observer see a star when it is located below the horizon?
Star B is always visible, star A is not visible at position 4
is either star A or B ever in an unobservable position, if so, what position?
imaginary plane
is the horizon a real, physical horizon or an imaginary plane that extends from your observing location earth out to the stars?
A3
Star A is just visible above your eastern horizon at position 1. At which numbered positions is it just visible above your western horizon
Student 2 (only star A's path carries it below the horizon for the observer)
two students are discussing weather or not star B rises and sets, Student 1: locations B1 and B3 are on my horizon because they are rising and setting like A1 and A3 Student 2: Figure 1 shows that star B is as low as it will get when it just below the horizon who do you agree with?
rising
when a star travels from a position above the observer's horizon to a position below the observers horizon, is that star rising or setting?
setting
when a star travels from a position above the observers horizon to a position below the observers horizon, is that star rising or setting?
