Polaris is the star which aligns with the rotational axis of the Earth.
Further, by locating the rotational axis of the DMO coaster and rod assembly near the flexion/extension axis of the biomimetic spine, the applied torso load did not create any additional bending moment minimizing the effort require to move while wearing the DMO device.
Roughly speaking it is the field of a magnetic dipole currently tilted at an angle of about 10 degrees with respect to Earth's rotational axis, as if there were a bar magnet placed at that angle at the center of the Earth.
Its rotational axis -- corresponding to the spin -- points into the direction of propagation.

Hubbard explained that researchers believe the atmospheric disturbances are more numerous on Jupiter and Saturn but less strong compared to Uranus and Neptune, for reasons that may have to do with the planets' different compositions and their angles between the magnetic fields and rotational axis.
While Mercury is extremely close to the sun it does not have a rotational axis, according to NASA, which means there are regions in the north and south poles that do not get sunlight and would allow for ice to develop.
They have strong magnetic fields and, in a mechanism not yet fully understood, they produce energetic bipolar outflows along the rotational axis of the star which impinge on the surrounding clouds of gas and dust.
