We consider a variation on the problem of determining the
chromatic number of the Euclidean plane and define the

-unit distance graph to be the
graph whose vertices are the points of E
2, in which
two points are adjacent whenever their distance is within

of 1.
For certain values of

we are able to show that
the chromatic number is exactly 7.
For some smaller values we show the chromatic number is at least
5.
We offer a conjecture, with some supporting evidence,
that for
any

> 0 the chromatic number is 7.
