On the day of new moon, the moon rises when the sun rises. It sets when
the sun sets. It crosses the sky with the sun during the day.
Once each month, the moon comes all the way around in its orbit so that it is
more or less between us and the sun. If the moon always passed
directly
between the sun and Earth at new moon, a solar eclipse would take place
every month. But that doesn’t happen every month. Instead, in most
months, the moon passes above or below the sun as seen from our earthly
vantage point.
Then a day or two later, the moon reappears, in the west after sunset. Then it’s a slim waxing crescent visible only briefly after sunset – what some call a
young moon.
