Is there a minimum wavelength in a black body's radiation? If yes, is there a formula to calculate it?

In this image from Wikipedia, it does seem that the curve is touching the x-axis rather than being an asymptote, so I feel there should be a minimum wavelength.

No... Or rather: Yes, Zero.

It's not. The curve approaches zero rather quickly. So, it's hard to illustrate.
