These authors predicted that, given its high axial tilt
, changes in the geometric aspect of Pluto dominate the observed changes in the amplitude of the rotational lightcurve.
Figure 2 shows what happens when a dedicated center-channel speaker sits below the TV with no axial tilt
toward the listener and high-quality speakers are used.
Workpieces are drawn between the two wheels by an axial tilt
of the regulating wheelhead (up to 5 degrees on a Landis(R) 8RE-2(TM) grinder).
means that during certain parts of our orbit around the sun, the Northern Hemisphere is tipped more towards Earth than the Southern Hemisphere, making it summer for half the planet; then, in another part of the cycle, we're tilted back away from the sun.
While it is merely a coincidence that the eclipse falls on the same date as this year's winter solstice, for eclipse watchers this means that the moon will appear very high in the night sky, as the solstice marks the time when the Earth's axial tilt
is farthest away from the sun.
These seasonal changes are caused more by the planet's 248-year elliptical orbit than (as in the case of Earth) by its axial tilt
