The farthest spacecraft from Earth, NASA’s Voyager 1 (see notes 1) probe took a photo of planet Earth on February 14, 1990, from a record distance of about 6 billion kilometers (3.7 billion miles, 40 AU (see notes 2) from Earth. The photo is known as the Pale Blue Dot. In the photograph, Earth is shown as a fraction of a pixel (0.12 pixel in size) against the vastness of space. It was a part of the Solar System Family Portrait series of images.
