To reach the potentially habitable planet
Proxima b, these «photogravitational» assists counterintuitively require first sending the light sail swooping blisteringly close to the bright, sunlike
stars Alpha Centauri A and B — even though they are nearly two trillion kilometers farther from us than
Proxima b's smaller, dimmer
host star,
Proxima Centauri.
In addition, all three
stars (including Proxima) were among the «Tier 1» target stars for NASA's optical Space Interferometry Mission (SIM) to detect a planet as small as three Earth - masses within two AUs of its host star (and so some summary system information and images on Stars A, B, and C are available from the SIM Teams), but the SIM project manager announced on November 8, 2010 that the mission was indefinitely postponed due to withdrawal of NASA fun

Proxima has been selected to be one of the Tier 1 target
stars for NASA's Space Interferometry Mission (SIM)-- which is planned for launch as early as 2011 — to detect a planet as small as three Earth - masses within two AUs of its
host star.
An international team of 31 scientists found the planet after careful and repeated measurements of slight shifts in the color of the light coming from its
host star,
Proxima Centauri, which is a small, dim
star in the Alpha Centauri system.
