• 2. Home - The Inner Solar System
• Let us start with the inner Solar System. This is something that we have some idea about. It consists of the four planets (show them) Mercury, Venus, Earth and Mars. The diameter of the Earth’s orbit is 300,000,000 km (180,000,000 miles).
• Just to put this into perspective, most new cars will travel about 150,000 km (100,000 miles) before they wear out. The distance we are talking about is 2,000 times larger than that. Kilometers (or miles) are too small for these measurements so we often call it, 2 Astronomical Units. One Astronomical Unit or A.U. is the average distance between the Earth and the Sun.
