RAM stands for random-access memory, which makes it possible to find specific information very quickly. It is a form of fast-access, volatile storage that is used as the main memory in computer systems. The most widely used form of RAM for the main memory is dynamic RAM (DRAM).

Its data suggests Proxima b has a minimum mass 1.3 times that of Earth and orbits at a distance of about 7.5 million km from the star, taking 11.2 days to complete one revolution. The distance between the star and its planet is considerably smaller than Earth's separation from the Sun (149 million km). But Proxima Centauri is what is termed a red dwarf star. It is much reduced in size and dimmer compared with our Sun, and so a planet can be nearer and still enjoy conditions that are potentially as benign as those on Earth. This planet is at 5% of the Earth's distance from the Sun.
