When the Sun, Moon and Earth lie roughly in a straight line it’s called a syzygy. Two common consequences:
- Eclipses:
- Moon between Sun and Earth (new moon) — a solar eclipse can occur if the alignment is exact.
- Earth between Sun and Moon (full moon) — a lunar eclipse can occur if the alignment is exact.
(Eclipses don’t happen every new/full moon because the Moon’s orbit is tilted about 5°.)
- Tides: at new and full moons the Sun’s and Moon’s gravity reinforce each other, producing spring tides (higher high tides and lower low tides).
