Proxima Centauri is the nearest star to Earth after the Sun, ... Then the probes would take photos and collect data of the planets of the stars, and their atmospheric ...
Proxima Centauri b is the closest exoplanet to Earth, [19] at a distance of about 4.2 ly (1.3 parsecs). [4] It orbits Proxima Centauri every 11.186 Earth days at a distance of about 0.049 AU, [1] over 20 times closer to Proxima Centauri than Earth is to the Sun. [20] As of 2021, it is unclear whether it has an eccentricity [e] [23] but Proxima Centauri b is unlikely to have any obliquity. [24]

The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A , which is also the brightest star in Earth's night sky ; its white dwarf companion Sirius B is the hottest object among them.
The planet, dubbed Proxima b because it orbits Proxima Centauri, is thought to be a rocky and slightly more massive than Earth -- but that's not all. The planet, dubbed Proxima b because it orbits ...
English: The two bright stars are (left) Alpha Centauri and (right) Beta Centauri, both binaries.The faint red star in the center of the red circle, to the lower left from the center point between Alpha and Beta, and southwest of Alpha, is Proxima Centauri, intensely red, smaller in size, weaker in brightness and a distant third element in a triple star system with the main close pair forming ...
The European Southern Observatory (ESO) announced the detection of a planet orbiting the third star in the Alpha Centauri system, Proxima Centauri in August 2016. [15] [16] The planet, called Proxima Centauri b, orbits within the habitable zone of its star. It could be a target for one of the Breakthrough Initiatives' projects.
English: This plot shows how the motion of Proxima Centauri towards and away from Earth is changing with time over the first half of 2016. Sometimes Proxima Centauri is approaching Earth at about 5 kilometres per hour — normal human walking pace — and at times receding at the same speed.
