planet whose orbit lies inside that of the earth. There are two inferior planets, Mercury and Venus.
Inferior Planet
The inferior planets are those which orbit closer to the Sun than the Earth, namely Mercury and Venus. They are seen to undergo phases ranging from crescent to full, and also exhibit retrograde motion.

Inferior Planets are those located inside of the Earth's orbit and include Venus and Mercury. Their main alignments are shown in Figure 16.

Copernicus was from Poland, but there is some debate among ethnic nationalists over whether he should properly be considered ethnically Polish or German.
Since Venus is an inferior planet, it shows phases when viewed with a telescope from the perspective of Earth. Galileo's observation of this phenomenon was important evidence in favor of Copernicus's heliocentric theory of the solar system.

The term inner planet should not be confused with inferior planet, which designates those planets which are closer to the Sun than Earth is (i.e. Mercury and Venus).
inferior planets The planets Mercury and Venus are inferior planets because their orbits are closer to the Sun than is Earth's orbit. interplanetary magnetic field (IMF) The magnetic field carried with the solar wind.
Definition: conjunction: An inferior planet (closer to the sun than Earth - Mercury and Venus) is said to be "in inferior conjunction" when it is directly between the Earth and the Sun.
Mercury and Venus are inferior planets because their orbits are inside the orbit of the Earth. Thus, when watching from the Earth, they are never too far away from the Sun.
Comparing with the preceding diagram for the inferior planets, we notice two basic differences: (1) The superior planets do not exhibit a full range of phases; they are always gibbous or full.
While Mercury, the other inferior planet, reaches a maximum elongation of only 28¬ƒ and is often difficult to discern in twilight, Venus is hard to miss when it is at its brightest.
As seen from Earth, the inferior planets may exhibit the full range of phases from new (only the unilluminated hemisphere being visible) to full.
The inferior planets, and other objects with orbits closer to the Sun than the Earth, can never be at opposition.
A planet is in conjunction when the Sun is exactly between that planet and the Earth or, for Mercury and Venus (the two inferior planets), when that planet, the Sun, and the Earth are lined up.
