| | | | | | |
Sun, the ecliptic plane, over periods of
| | | | | |
hundreds of years, | |
a) |
remains fixed at an angle of 23.5° to the
| | | | | | | |
celestial equator. |
b) |
is coincident with the celestial equator,
| | | | |
by definition.
|
c) |
varies between angles of' +23.5 and -23.5°
| | | | | |
,from the celestial equator through the year,
| | | | | |
making an angle of 0° to the equator at
| | | | | | | |
midsummer and midwinter. - CORRECT ANSWER✔✔-a) | | | | | |
remains fixed at an angle of 23.5° to the
| | | | | | | |
celestial equator. |
As the Moon orbits the Earth and we observe
| | | | | | | |
its phases, how fast does the terminator (the
| | | | | | |
dividing line between illuminated and dark
| | | | |
parts of the Moon) move across the lunar
| | | | | | |
surface, in terms of angle of lunar longitude?
| | | | | | | |
a) |
360 degrees in about 1 year, or about 1
| | | | | | | |
degree per day. | |
b) |
360 degrees in about 1 month, or about 12
| | | | | | | |
degrees per day. | |
,c) |
The terminator will never move since the
| | | | | |
Moon does not rotate with respect to the
| | | | | | |
Earth. - CORRECT ANSWER✔✔-360 degrees in about 1 month, or about
| | | | | | | | | | |
12
degrees per day. | |
