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).
English: Size comparison between VY Canis Majoris and Earth (via the Sun) by zooming in three times. The colours of the stars have been chosen based roughly on their surface temperatures.nglish: Size comparison between VY Canis Majoris and Earth (via the Sun) by zooming in three times.

To illustrate, if Earth's Sun were replaced by VY Canis Majoris, its radius might extend beyond the orbit of Saturn (about 9 AU). Assuming the upper size limit of 2100 solar radii, light would take more than 2.7 hours to travel around the star's circumference, compared to 14.5 seconds for the Sun.It would take 7 1015 Earths to fill the volume of VY Canis Majoris.ssuming the upper size limit of 2100 solar radii, light would take more than 2.7 hours to travel around the star's circumference, compared to 14.5 seconds for the Sun.
