Using the latest imagery consisting of a global mosaic covering 97.7% of this elusive world, Mercury Atlas displays the phase and central meridian of Mercury from your chosen location and time. The feature database contains over 320 currently named features and is searchable.

You can switch to a 'Globe' mode that allows you to spin Mercury around to see the whole globe.

Use pinch and finger gestures to manipulate a 3D globe of Mercury. As you zoom in more labels appear as finer detail comes into view. You can double tap on the labels to get more information about a particular feature.

Date, time and location can be changed. There is also a realtime mode that will update to the current time.

The Mercury globe can be shown with north or south at the top or inverted to suit different telescope views and the phase can be switched off to show the whole globe more clearly.

You can swipe left and right on the phase view to go backwards and forwards a day.

Moon, Mars and Venus atlases are also available on the App Store!
