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).

VY Canis Majoris is a high-luminosity M star with an effective temperature of about 3,500 K, placing it at the upper-right hand corner of the HertzsprungâRussell diagram and meaning it is a highly evolved star. During its main sequence, it would have been an O-type star with a mass of 15 to 35 Mâ .t has an average density of 5 to 10 mg/m 3. If placed at the center of the Solar System, VY Canis Majoris's surface would extend beyond the orbit of Jupiter, although there is still considerable variation in estimates of the radius.
