Which horizon does the moon rise

Each moonrise, then, will occur roughly 52 minutes later than the one before it. Because the phase of the Moon also depends on its position relative to Earth and the Sun, the phase will change along with the time that the Moon rises and sets.

Just as Earth is tilted with respect to its orbit around the Sun, the Moon is tilted with respect to its orbit around Earth.

Over the next few days, as the Moon shrinks back down to a "crescent", it rises later every night. Eventually we catch only a glimpse of it at sunrise, coming over the horizon just before the Sun. Note that crescent strictly means "growing"; the Moon should really be called decrescent at this phase. If you know how many days it is since New Moon, multiply that by 50 minutes, to find out approximately how much the Moon is lagging behind the Sun.

It will only be approximate, because the Moon's orbit is an ellipse rather than a circle, and it doesn't go round at a constant speed. So the Moon crosses the sky about 50 minutes later every day. And you might think it would rise 50 minutes later every day, and set 50 minutes later too. But this isn't true - because the Moon doesn't spend the same length of time above the horizon every day.

The Sun goes through a seasonal variation, once a year. In December and January, the Sun is in the far south of the sky. It rises in the south-east; it spends only a few hours above the horizon for northern-hemisphere observers , crossing the sky quite low down; and it sets in the south-west.

In June and July, the Sun is in the far north of the sky. It rises in the north-east ; it spends many hours above the horizon for northern-hemisphere observers , crossing the sky quite high up; and it sets in the north-west. The Moon follows the same cycle, but about twelve times faster; it gets round in about a month. The Moon is in the same place as the Sun at New Moon.

As we have seen, the time at which the Moon crosses the southern sky gets later every day, by about 50 minutes.
