The place in which a planet whose orbit is inside that of the Earth, passes between the Earth and the Sun
An alignment of the Sun and any two planets such that an observer on the outer planet sees the inner planet positioned between himself and the Sun. For example, Venus is at inferior conjunction when it is positioned between Earth and the Sun.
The passage of Mercury or Venus between Earth and the Sun. The outer planets cannot pass between Earth and the Sun and therefore cannot come to inferior conjunction.
Alignment of Earth, Sun, and an inferior planet on the same side of the Sun.
When Mercury, or Venus, are directly between the Sun and Earth.
the configuration of an inferior planet when it lies between the sun and Earth
A conjunction of an inferior planet that occurs when the planet is lined up directly between the Earth and the Sun.
The point at which, as viewed from some planet, an inferior planet lies directly in between the Sun and the planet at which the observation is being made. At this point, the inferior planet is obviously unobservable, unless the line-up is perfect, in which case a transit will be observed.
position of an inferior planet, as viewed from Earth, when it is between the Sun and Earth.
