It's absolute zero, where there is no heat, and therefore no movement of particles. It is -273 C.

Absolute zero is a theoretical temperature. It is that temperature at which all substances have no heat energy. It is defined as zero Kelvin (0 Kelvin). 0 Kelvin is equivalent to -273.16 degrees Celsius, and -459.69 degrees Fahrenheit .
Temperatures in our universe range from about 3,500,000,000 Kelvin (a supernova) to about 3 Kelvin (space). Our Sun is a class G yellow star and has an average surface temperature of 5,600 Kelvin.

Zero kelvin is the temperature wher all moves are cancelled . At that temperature, molecules and atoms are at rest.
Its value in celsius is -273.16°C

zero kelvin is as cold as it can get

i'd go further, it's not just where particles stop moving it is the state where there is no energy present at all. so presumably even sub atomic particles stop moving (electrons and quarks etc). nothing will happen at all, at least till someone says 'let there be light' ;)
can only assume it's impossible to get to this point though not sure how close you can get.

this is the absolute zero, the temperature at which there is absolutely no molecular movement.
I think it's -258C

Cold enough where you could probably snap a steel rod in half with your (gloved, of course) hands.
