View of Earth and Moon from Mars

View of Earth and Moon from Mars
Think about yourself standing on planet Mars and looking towards our Earth. If you are lucky enough, you may be able to see something like the picture above. Yes, you will be able to see both Earth and Moon in the same sky. Though it is not possible to get there physically, we can use our advanced spacecrafts to take pictures of views like this.

The above image was taken n October 3, 2007, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. At the time the image was taken, Earth was 142 million kilometers (88 million miles) from Mars, giving the HiRISE image a scale of 142 kilometers (88 miles) per pixel, 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 disk of the Earth and the disk of the moon have direct illumination.
