4.3 Sol System
An annotated chart of the Sol system presents physical data for the Sun and each planet (Mercury, Venus, Earth, the Moon, Mars, the asteroid belt, Jupiter, Saturn, Uranus, Neptune, Pluto) along with comets, the Mars Defense Perimeter, and a timeline of milestone launches from Sputnik through Friendship One.
Chart of the Sol system showing the Sun and inner planets (Mercury, Venus, Earth, Moon, Mars), the asteroid belt, the Mars Defense Perimeter, and the routes of the Borg cube (2372) and the Phoenix (2063).
Comparative sizes of the planets and the outer Sol system (Jupiter, Saturn, Uranus, Neptune, Pluto) with comets, the size of the Sun, and the routes of V'Ger (2271), the Vulcan survey ship (2063), and the Breen attack (2375).
