  We examine the angular distributions of near-Earth objects (NEOs) which are
often regarded as uniform. The apparent distribution of the longitude of
ascending node, $\Omega$, is strongly affected by well-known seasonal effects
in the discovery rate of NEOs. The deviation from the expected
$\pi$-periodicity in the apparent distribution of $\Omega$ indicates that its
intrinsic distribution is slightly enhanced along a mean direction,
$\bar\Omega=111^\circ$; approximately 53% of NEOs have $\Omega$ values within
$\pm90^\circ$ of $\bar\Omega$. We also find that each sub-group of NEOs (Amors,
Apollos and Atens) has different observational selection effects which cause
different non-uniformities in the apparent distributions of their arguments of
perihelion $\omega$, and longitudes of perihelion $\varpi$. For their intrinsic
distributions, our analysis reveals that the Apollo asteroids have non-uniform
$\omega$ due to secular dynamics associated with
inclination-eccentricity-$\omega$ coupling, and the Amors' $\varpi$
distribution is peaked towards the secularly forced eccentricity vector. The
Apollos' $\omega$ distribution is axial, favoring values near 0 and
$180^\circ$; the two quadrants centered at 0 and $180^\circ$ account for 55% of
the Apollos' $\omega$ values. The Amors' $\varpi$ distribution peaks near
$\bar\varpi=4^\circ$; sixty-one percent of Amors have $\varpi$ within
$\pm90^\circ$ of this peak. We show that these modest but statistically
significant deviations from uniform random distributions of angular elements
are owed to planetary perturbations, primarily Jupiter's. It is remarkable that
this strongly chaotic population of minor planets reveals the presence of
Jupiter in its angular distributions.
