New picture of the Earth c the orbit of Mars shows the ratio of the size of our planet and the moon.
At the time of the shooting, Mars and Earth were separated a distance of approximately 204 million kilometers.
The picture was taken in the framework of the calibration camera of the Mars Reconnaissance Orbiter. The image is assembled from a pair of images acquired on 20 November 2016 scientific instrument HiRISE.
It took to correct the images due to the difference in the brightness of the moon and Earth satellite is much darker and would be lost in the reflected light of our planet.
The image is also interesting for its unusual perspective. The fact that the picture was taken at a time when the Moon was almost directly behind the Earth from the perspective of a Martian observer. So it seems that the Moon is much closer to the Earth than it actually is.
