  Radiation of both the outer gaps and the neutron star surface is considered
for a Vela-like pulsar near the death line. It is shown that if such a pulsar
is close enough to the death line, its optical, UV and X-ray emission has to
increase. Using results of this consideration, it is argued that Geminga is not
a close relative of Vela-like pulsars. The outer gap model of Geminga in which
the main part of the outer gap volume operates as a Vela-like generator of
$\gamma$-rays is ruled out. A Vela-like mechanism of $\gamma$-ray generation
can operate only in a small region of the outer gap of Geminga. The length of
this region along the magnetic field is an order of magnitude smaller than the
outer gap dimensions. In the magnetosphere of Geminga the main mechanism of
$\gamma$-ray generation at $\sim 10 - 10^4$ MeV is curvature radiation and not
the synchrotron radiation as it was assumed for Vela-like pulsars.
