Why is there a small lower limit to temperaure (-273.15C) but almost limitless upperbound? (million of degree in a star for example)

Is there even an upper limit to temperature?

In addition to the other answers, I would like to note that 0°C being where it is is ultimately arbitrary. Make no mistake, there were valid reasons to set it there, but it was still a decision made by people, rather than anything meaningful on a cosmic scale.

If we were to use a temperature scale with the 0 point at the temperature of a main sequence star, then absolute zero would be close to -5000°, and probably wouldn’t look so small.
