  New astrometric analysis of four WFPC2 images of the isolated neutron star RX
J185635-3754 show that its distance is 117 +/- 12 pc, nearly double the
originally published distance. At the revised distance, the star's age is 5 x
10^5 years, its space velocity is about 185 km/s, and its radiation radius
inferred from thermal emission is approximately 15 km, in the range of many
equations of state both with and without exotic matter. These measurements
remove observational support for an extremely soft equation of state. The
star's birthplace is still likely to be in the Upper Sco association, but a
connection with zeta Oph is now unlikely.
