Uranus is about the point where our cosmic coach would call in an interplanetary field goal kicker. Now considered the eighth and final planet in the solar system is Neptune, the fourth largest planet with a radius of 15,389 miles (24,766 km). • Assign each group a different scale* (1mm= 100km, 1 mm = 1000 km, 1 mm = 10000 km, 1 mm = 100000 km, 1 mm = 1000000 km). 1.5 mm - length of average flea. VENUS Actual Diameter - 12,104 km. A model of the 8 planets of the solar system to true scale to one another. 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 is the third-largest planet in the Solar System, and it has a diameter of around 51.118 km / 31.763 mi and a radius of 25.362 km / 15.759 mi. Part 2 Now let's consider which scale factor is more appropriate. Measure the diameter of a quarter 28 : Europa . 18.6 mm = 18.8 ÷ 10 = 1.86 cm Then, convert by scaling 1.86 cm × 50 ÷ 1 = 93 cm On this scale, the Sun's diameter is 0.01 inch = 0.25mm, smaller than the width of 1 pin! It would take around 63 Earth-sized planets to fill Uranus, and yes, that sounds dirty. Because the distance scale model only is concerned about distances between the planets, you can make all the planets the same size. For example, if the earth were a paper plate (about 9 inches, or 228 mm) the rest of the system would be scaled as shown on the sample table below. Scale planet diameter (m)/ scale sun diameter (m) = actual planet radius (km)/actual sun radius (km) Complete the calculations for the other planets in the same manner, then convert the scale sizes to cm and mm. A 90mm telescope will offer you with a clear view of Saturn and its rings, as well as Uranus, Neptune, and Jupiter, which will be visible with its Great Red Spot. URANUS 51 118 NEPTUNE 49 523 * Scale factor is 1 to 10 billion. The table shows the diameters of the outer planets compared to Earth. Additionally, if you wanted to include the sun in this model, you'd need a basketball.) Neptune. Show your work. To help compare different orders of magnitude, this section lists lengths between 10 −3 m and 10 −2 m (1 mm and 1 cm). At this scale the Sun is about the size of a soccer ball, the Earth is about the size of a peppercorn, and Pluto is a grain of salt . On this scale, The Earth is about 150 meters from the Sun and is 1.2 cm in diameter. take the diameter of each planet in km and change the scale to mm and then use that to estimate which model is closest to that scale size. Measure the diameter of the ball using the large calipers. After Earth's, the next two largest diameters belong to Neptune at 30,778 miles and Uranus at 31,763 miles. How to calculate scale size.
