Consider, though, the plight of observers who favor the so-called inferior planets, Mercury and Venus, which circle the Sun inside Earth's orbit and thus never have oppositions.
Of the two inferior planets, Mercury, because of its unusual orbit, requires a special solution to the problem of the equant.
The possibility that the inferior planets might occasionally pass in front of the Sun was not considered until the early part of the seventeenth century, when Kepler predicted transits of both Mercury and Venus for 1631.
