This arbitrary sphere appears to rotate westward around a polar axis due to Earth's rotation.
Astronomical tables and websites, such as Heavens-Above, forecast when and where the planets reach their next maximum elongations. Sometimes elongation may instead refer to the angular distance of the Moon relative Earth or the natural satellite of another planet from its central planet, for instance the angular distance of Io from Jupiter.
