Orbital pole

The north orbital pole of a revolving body is defined by the right-hand rule.

For the remaining planets, the orbital pole in ecliptic coordinates is given by the longitude of the ascending node (☊) and inclination (i): ℓ = ☊ − 90° , b = 90° − i .

The continuous viewing zone (CVZ) of the Hubble Space Telescope lies inside roughly 24° of Hubble's orbital poles, which precess around the Earth's axis every 56 days.

It is impossible anywhere on Earth for either ecliptic pole to be at the zenith in the night sky.

The ecliptic poles can contact the zenith only within the Arctic and Antarctic circles.

The north orbital poles of the Solar System major planets all lie within Draco . [ 1 ] The central yellow dot represents the Sun 's rotation axis north pole. [ citation needed ] Jupiter 's north orbital pole is colored orange, Mercury 's pale blue, Venus 's green, Earth 's blue, Mars 's red, Saturn 's magenta, Uranus 's grey, and Neptune 's lavender. That of the dwarf planet Pluto is shown as the dotless cross off in Cepheus .
