Moon Position Map
Quick answer: The blue marker is where the moon is directly overhead at this moment. The moon's phase, distance, and declination are shown below the map.
How to use moon position map
- Select the observing location, rather than the place where you want the Moon to be overhead.
- Set local date and time. The compass and altitude update together.
- Check rise/set times and illumination before planning an observation. Copy the selected instant to share it.
Worked example
- Input
- Moon azimuth 90°, altitude 25°
- Expected result
- Look east, about 25° above a flat horizon.
The overhead-Moon marker identifies a location on Earth. It is not the direction to look from your own location.
Calculation method and accuracy
Local azimuth, refraction-adjusted altitude and Earth–Moon distance come from SunCalc. Moonrise/set events are computed for adjacent UTC dates, then filtered to the selected local calendar day. The purple map marker uses an approximate sublunar position; use the local compass for the observer’s direction.
Common mistakes and edge cases
- The Moon can be below your horizon even when the global phase is full.
- Some dates have only a rise or only a set. A missing event does not automatically mean the Moon stays below the horizon all day.
- Buildings, terrain, weather and atmospheric refraction affect actual visibility near the horizon.

What the sub-lunar point means
The sub-lunar point is the place on Earth where the moon is exactly overhead — the point an observer would have to stand at to see the moon at 90° elevation. It moves west as the Earth turns and north or south as the moon's declination changes.
Because the moon's orbital plane is tilted about 5° from the ecliptic, its declination ranges further than the sun's, reaching about ±28.7° rather than the sun's ±23.4°.
Why the moon rises later each day
The moon moves eastward against the stars by about 13° per day as it orbits. The Earth has to rotate a bit further to bring the moon back to the same place in the sky, which works out at roughly 50 minutes of extra rotation — hence the later rise.
Distance varies noticeably
The moon's orbit is elliptical, so its distance swings between about 356,500 km at perigee and 406,700 km at apogee. A full moon near perigee appears around 14% wider and 30% brighter than one at apogee, which is what the term supermoon refers to.
Limitations to keep in mind
The position uses a low-precision lunar ephemeris with the principal periodic terms, accurate to about a degree. That is fine for a world map marker but not for occultation timings or precise rise and set predictions.

Frequently asked questions
- Where is the moon right now?
- The tool marks the sub-lunar point: the place on the globe where the moon is directly overhead. It updates from the current time.
- What is declination?
- The moon's angular distance north or south of the celestial equator. It is roughly equivalent to latitude for the sub-lunar point on the ground.
- Is the moon ever directly overhead where I live?
- Only if your latitude falls within the moon's declination range, which is about ±28.7°. Outside that band, the moon always stays somewhat north or south of overhead.
- Why does the moon rise at a different time each day?
- Because it orbits eastward by about 13° per day, so the Earth must rotate further to bring it back into view. The rise time shifts by roughly 50 minutes daily.
- How far away is the moon?
- On average about 384,400 km, but it varies from roughly 356,500 km at perigee to 406,700 km at apogee.
- What is a supermoon?
- A full moon occurring near perigee, when the moon is closest. It appears slightly larger and noticeably brighter than an average full moon.
- Does the map show the moon's phase?
- Yes, the phase name, illuminated percentage, and moon age are shown in the results below the map.
- Why does the moon's path across the sky change?
- Because of the 5° tilt of its orbit relative to the ecliptic combined with the Earth's axial tilt. The result is a declination cycle that runs through a longer 18.6-year pattern.
- Is this live?
- It is calculated for the time the page loads. Reload to refresh the position.
- Can I see the moon during the day?
- Yes, for roughly half of every day. The moon is above the horizon about as often in daylight as at night; it is just easier to notice against a dark sky.
