Earth
Where is the Moon above the horizon? Explore Earth
The Earth view reverses your perspective. Rather than looking up from your location, see on a world map where a celestial object is above the horizon.
- Where is it night?
- Where is the Moon above the horizon?
- Where on Earth is the Sun overhead?
- Where does the next solar eclipse path run?
Day, night and twilight
A detailed solar-altitude map shows the day–night boundary and the zones of civil, nautical and astronomical twilight.
Above-horizon regions
For each object, the map marks the region where it is above the horizon and the point where it is directly overhead. For the Moon, this is called the sublunar point.
Eclipse paths
During solar eclipses, the map plots the umbral or antumbral region, the central line with time markers at roughly ten-minute intervals and lines of equal obscuration.

Frequently asked questions
Does the Earth view need internet access?
Map tiles do; the app calculates the astronomical layers on your device.
What is the sublunar point?
The location on Earth where the Moon is directly overhead, at the zenith.
Can the map help with lunar eclipses?
A lunar eclipse can be observed from places where the Moon is above the horizon during the eclipse. The Moon’s above-horizon region shows the relevant part of Earth; your local horizon still matters.
