3Orbital distance = 2 x 3.14 x 148,800,000 km Orbital distance per day = km= 2,560,000 kmOrbital speed per hour = km/h= 107,000 km/h
4The Moon Orbital period = 28 days Distance from Earth = 384,000 km Orbital distance = 2 x 3.14 x 384,000= 2,411,520 kmOrbital distance per day = km= 86,136 kmOrbital speed per hour = km/h = 3589 km/hThis is 1 km/s
5Which is Fastest? radius x 2 x 3.14 circumference or orbiting distance around the Sun number of days or orbital perioddistance planet travels per day (Earth day!) 24speed of planet in km/h (Earth hour!)Which is Fastest?
