44m. 2s. S= 29. 53 days. The sidereal month is about two days shorter, being 27d. 7h. 43m. Lls. 5. Or 27. 32 days. As the sun and moon are both revolv- ing in the same direction, and the sun is moving nearly 153. How much of the moon is illuminated at once? Ex- plain the phases of the moon from figure 31.
1 54. Define a month. Define a sidereal month. Also a sy- nodical month. Why so called ? What is the length of the Bynodical month ? Also of the sidereal month ? What is the moon's daily motio...n ?
REVOLUTIONS. 123 a degree a day, during the 27 days of the moan's revo- lution, the sun must have moved 27. Now since the moon passes over 360 in 27. 32 days, her daily motion must be 13 17'. It must therefore evidently take about two days for the moon to overtake the sun.
155. The moon's orbit is inclined to the ecliptic in an angle of about 5 (5 8' 48". ) The moon crosses the ecliptic in two opposite points called her nodes. That which the moon crosses from south to north, is called her ascending node, that which she crosses from north to south, her descending node.
