In which positions would a first quarter moon and last quarter moon appear to an observer on Earth?
A First quarter: position 1
Last quarter: position 5
R First quarter: position 2
Last quarter: position 6
First quarter: position 3
Last quarter: position 7
0 First quarter: position 4
Last quarter: position 8
(diagram is 8 positions in a counter clockwise circle)
So, a first quarter moon would appear at positions 1, 2, 3, or 4, while a last quarter moon would appear at positions 5, 6, 7, or 8.
the sunlight is coming from the rightof the diagram btw
In that case, a first quarter moon would appear at positions 4, 5, 6, or 7, while a last quarter moon would appear at positions 1, 2, 3, or 8.
only one position eacj
Apologies for the confusion. With sunlight coming from the right, the positions for a first quarter moon and last quarter moon on the diagram would be:
- First quarter: Position 4
- Last quarter: Position 8
