- Planetary_phase abstract "The two inferior planets, Mercury and Venus, which have orbits that are smaller than the Earth's, exhibit the full range of phases as does the Moon, when seen through a telescope. Their phases are "full" when they are at superior conjunction, on the far side of the Sun as seen from the Earth. (It is usually possible to see them at these times, since their orbits are not exactly in the plane of Earth's orbit, so they usually appear to pass slightly above or below the Sun in the sky.) Their phases are "new" when they are at inferior conjunction, passing more or less between the Sun and the Earth. (Sometimes they appear to cross the solar disk, which is called a transit of the planet.) At intermediate points on their orbits, these planets exhibit the full range of crescent and gibbous phases.The superior planets, orbiting outside the Earth's orbit, do not exhibit the full range of phases. However, Mars often appears significantly gibbous, when it is illuminated by the Sun at a very different angle than it is seen by an observer on Earth, so an observer on Mars would see the Sun and the Earth widely separated in the sky. This effect is not easily noticeable for the giant planets, from Jupiter outward, since they are so far away that the Sun and the Earth, as seen from these outer planets, would appear to be in almost the same direction.".
