Which bodies were considered planets in the initial geocentric model besides Mercury, Venus, Mars, Jupiter, and Saturn?
The Sun and the Moon
In the long-standing geocentric model, the definition of what constituted a planet was much broader than the modern understanding, reflecting Earth's central position in the cosmos. This early roster included the seven observable moving lights in the sky. These were the five classical planets known today—Mercury, Venus, Mars, Jupiter, and Saturn—but crucially, the count also encompassed the Sun and the Moon. In that historical framework, these two major celestial bodies were classified as planets because they visibly moved across the sky relative to the background stars. When the heliocentric model gained acceptance, displacing Earth from the center, the Sun and Moon were removed from the planetary count, leaving only the five known moving bodies orbiting the central star.
