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).

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.

Mass of VY Canis Majoris is [math]59.67*10^{30}[/math] kg (~30 Solar mass) Mass of Earth is [math]5.972*10^{24}[/math] kg To make it easier we will imagine that orbit around VY Canis Majoris is perfectly circular (this is an imaginary situation after all). Main equation for speed in circular orbit (as per wiki Circular orbit article) is:
