Moon Phase Today: July 17, 2021

The Moon's current phase for today and tonight is a First Quarter phase. This phase occurs roughly 7 days after the New Moon when the moon is one quarter of the way through its orbit around the earth. Exactly half the moon will be illuminated and half dark. On the day of the First Quarter phase the moon is high overhead at sunset and is visible until mid-night when it sets in the west. The First Quarter phase is a one-day event and in the following days enters a Waxing Gibbous phase becoming more illuminated each day until the Full Moon.

Buck Moon after 6 days
Next Full Moon is the Buck Moon of July 2021 after 6 days on 24 July 2021 at 02:37.

Syzygy in 6 days

After 6 days on 24 July 2021 at 02:37 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.

Neap tide

There is low ocean tide today. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Distance to Moon 366 475 km

Moon is 366 475 km (227 717 mi) away from Earth on this date. Moon moves closer next 3 days until perigee, when Earth-Moon distance will reach 364 520 km (226 502 mi).

Moon before perigee

11 days after point of apogee on 5 July 2021 at 14:48 in ♉ Taurus. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 3 days, until it get to the point of next perigee on 21 July 2021 at 10:30 in ♐ Sagittarius.

Moon before southern standstill

8 days after previous North standstill on 9 July 2021 at 10:05 in ♋ Cancer, when Moon has reached northern declination of ∠25.622°. Next 5 days the lunar orbit moves southward to face South declination of ∠-25.643° in the next southern standstill on 22 July 2021 at 15:11 in ♑ Capricorn.
