Welcome to Earth and Moon Viewer and Solar System Explorer.
You can view either a map of the Earth showing the day and night regions at this moment, or view the Earth from the Sun, the Moon, the night side of the Earth, above any location on the planet specified by latitude, longitude and altitude, from a satellite in Earth orbit, or above various cities around the globe.
Images can be generated based on a
full-colour
image of the Earth
by day and night, a
topographical
map of the Earth, up-to-date
weather satellite imagery, or
a composite
image of cloud cover superimposed on a map of the Earth, a
colour composite
which shows clouds, land and sea temperatures, and ice, or the
global distribution of
water vapour.
Expert mode allows you additional control over
the generation of the image. You can compose a custom
request with frequently-used parameters and save it as a
bookmark item in your browser.
Please consult the
Details for additional
information and answers to frequently-asked questions.
In addition to the Earth, you can also view the Moon from the Earth, Sun, night side, above named formations on the lunar surface. or as a map showing day and night. You can also make expert and custom images of the Moon. A related document compares the appearance of the Moon at perigee and apogee, including an interactive Perigee and Apogee Calculator.
You can view a variety of solar system objects whose surfaces have been imaged by spacecraft. For some objects, a variety of imagery is available and can be selected from the control panel. Day and night are not shown for solar system bodies because the ability to calculate the Sun's apparent position from them is not implemented.
You can view Mercury; Venus; Mars and its moons Phobos and Deimos; the asteroids Ceres and Vesta; and Pluto and its moon Charon.
You can view named features on any of the bodies named above.
The Earth and Moon Viewer would have been enormously more difficult to implement without the help of the software and imagery mentioned in the credits.
Windows users can create images like this in real time, on their own machines, as well as view the sky, stars at the horizon, the solar system, orbits of asteroids and comets, and more with Home Planet, my public domain Earth/Space/Sky simulator available for your downloading pleasure. Other public domain astronomy and space software available from the same site includes:
All of these packages and more can be located from my home page.
