It is posted on the wall a few yards down here. The orbit is strongly eccentric and it takes 500 years to circle the Sun. The large ball that you will use to represent the Sun will probably not have a diameter of 10 cm, so your scale factor for this lab will be: Show at least one sample calculation below the table. Use the table below to determine each planet's scaled diameter (in centimeters), scaled orbit radius (in centimeters), and scaled distance from Earth (in centimeters). Scaled Distance - 1.17 m.

If the dome of the Westmont Observatory (diameter 5.67 meters) represents the Sun, then Uranus should be in this location and have a diameter of 19.1 cm. 5. The average diameter across the planet is 30,598 miles (49,244 km), almost four times the diameter of Earth. The radius at the poles is 15,125 miles (24,341 km), slightly smaller than the equatorial radius of 15,388 miles (24,764 km). Complete calculations on scrap paper. Use the scale 7000 km = 1 cm to calculate the scale size of planets. Compare in Size? Distribute the Modeling the Sun/Earth System worksheet. [/caption] The diameter of Uranus is 51,118 km. Which planet is closest in size to Earth? 5.) 1 10 cm! Use the ruler to draw a line for the diameter. To construct a solar system model, enter 5 (for example) in the scale factor box, click "Earth diameter" and you will have all the dimensions in terms of the Earth's diameter. 1 10 cm 1 Mars 6,794 km A bit les than! Imagine you are going to make a scale drawing of the planets in the solar system and their distances from Earth. For convenience, the scale model distances for the planets are also given in miles so that a car odometer can be used to measure out the distances of the planets from the position of the . The first Image on your handout is a scaled drawing of the inner solar system: the Sun, Mercury, Venus, Earth and Mars. 51800. Jupiter's diameter is about 11 times that of the Earth's and the Sun's diameter is about 10 times Jupiter's. Pluto's diameter is slightly less than one-fifth of Earth's.

Round each answer to the tenths place. Use the 13.28 m piece of string to represent the sun by tying the ends together making a circle with the correct scale diameter. Now let's find the scaled diameter of Mars as an example. Once students have created their scale (i.e. The scale notation is the size of the model compared to the real, full-size aircraft called the "prototype". So, a solar system with a 5 inch Earth would have a Sun that is (look at the calculations) 546.49 inches (45.5 feet) in diameter and the Earth to Sun distance would be 58,703 inches (4,892 feet) - almost a mile! (Uranus´real diameter is 50,720 km = 50,720,000 m) CONCLUSION QUESTIONS.
