Wolf 359 stereoscopic pair

On 22 and 23 April 2020, the New Horizons (NH) spacecraft photographed the two nearby stars, Proxima Centauri and Wolf 359, as part of an experiment to measure the parallax of the two stars. Amateur astronomers from around the world, were invited to photograph the two stars at the same time. Their observations, when combined with the NH images, would allow the parallaxes of the stars to be measured and their distances from Earth established.For more information, see the NH Parallax Program web site:
