Planetary Perspective... | The Earth and Moon as Seen from Mars, 142 million km away, captured by the camera aboard the Mars Orbiter built by @nasa and the @universityofarizonaThe HiRISE instrument would make a great backyard telescope for viewing Mars, and we can also use it at Mars to view other planets, such as Jupiter or in this case, Earth and it’s moon.
• This is image was acquired at 5:20 a.m. MST on 3 October 2007, at a range of 142 million kilometers, which gives the HiRISE image a scale of 142 km/pixel and an Earth diameter of about 90 pixels and a Moon diameter of 24 pixels. The phase angle is 98 degrees, which means that less than half of the disks of the Earth and Moon have direct illumination.
