If you were to project the Earth's latitude and longitude grid directly out onto the 'celestial sphere' the plane of the Moon is tilted by 5degrees 8' and 43" to the ecliptic plane which is in turn tilted by 23degrees and 27' with respect to the equatorial plane of the Earth. This means that the Moon's plane intersects the Ecliptic at two points so that every month the Moon passes through the Ecliptic plane. It is at this time that solar and lunar eclipses can occur if other factors are also favorable. The Moon can be as far as 23d 27' + 5d 8' = 28d 35' North of the Earth's equatorial plane, or as little as -23d 27' - 5d 8' = -28d 35' south of the equatorial plane. This means that for latitudes of -28d 35' or + 28d 35' the Moon can pass directly overhead.
