1
All of the planets in our solar system revolve around our Sun. Today you will investigate the speeds at which they move around. Orbiting Our Sun

2

3
Orbital distance= 2 x 3.14 x 148,800,000 km = 934,464,000 km Orbital distance per day= km = 2,560,000 km Orbital speed per hour= km/h = 107,000 km/h

4
The Moon Distance from Earth = 384,000 km Orbital distance = 2 x 3.14 x 384,000 = 2,411,520 km Orbital period = 28 days Orbital distance per day= km = 86,136 km Orbital speed per hour= km/h = 3589 km/h This is 1 km/s

5
radius x 2 x 3.14 circumference or orbiting distance around the Sun number of days or orbital period distance planet travels per day (Earth day!) 24 speed of planet in km/h (Earth hour!)

6
Answers (Distances in Km)
