It rolls on 4 wheels, with twin's front wheels which is swivel & because of the small
size front wheels the maneuverability is very easy, you can take the stroller to
narrow areas & the wheels can absorb some of the terrain & bumps but is it is not for
extreme harsh surface like other stroller.
The placement and orbits of small, so - called
extreme trans - Neptunian objects, can help
narrow down the
size and distance from the Sun of the predicted ninth planet, because that planet's gravity influences the movements of the smaller objects that are far beyond Neptune.
