Lab: Scaling the Solar System Name: ________________________ Date: ________________ Hr: ____ Honors Earth Science Background: Currently there are 8 known major planets, plus an estimated thousand other smaller ones called “dwarf planets”. While many people can name the major planets and their order, most don’t know their relative location or distance from each other. Distances in space are tough to comprehend. To make it easier to compare distance, astronomers use the unit “AU” or “astronomical unit”. 1 AU = the average distance from Earth to the Sun = 150,000,000km Question: How are the major and dwarf planets arranged across the solar system? Hypothesis: Procedure: 1) Calculate the distance in AU each planet is from the Sun. 2) Calculate its football field distance from the Sun using the formula: 𝒀𝒂𝒓𝒅𝒔 𝒇𝒓𝒐𝒎 𝑮𝒐𝒂𝒍 𝑳𝒊𝒏𝒆 (𝑺𝒖𝒏) = 𝑫𝒊𝒔𝒕𝒂𝒏𝒄𝒆 𝒇𝒓𝒐𝒎 𝑺𝒖𝒏 (𝑨𝑼) 𝒙 𝟐. 𝟓𝟔 3) Place the planet you are assigned, on the correct yard line away from the Sun. 4) Plot all planets on the football field diagram on the back of this page. Observations: Table 1: Solar System Distances: Planet Mercury Distance (km) from Sun 58,000,000 Venus 108,000,000 Earth 150,000,000 Mars 228,000,000 Ceres 415,500,000 Jupiter 778,500,000 Saturn 1,430,000,000 Uranus 2,880,000,000 Neptune 4,500,000,000 Orcus 5,875,500,000 Pluto 5,922,000,000 Salacia 6,328,335,000 Haumea 6,469,500,000 Quaoar 6,510,750,000 Makemake 6,868,500,000 Eris 10,150,500,000 Sedna 77,700,000,000 Distance (AU) from Sun Football field distance from Sun (yards) Lab: Scaling the Solar System Honors Earth Science Name: ________________________ Date: ________________ Hr: ____ Sketch (nearly) all planets on the football field below S U N Analysis Questions: 1. Describe where: a. the 4 inner planets were found on the football field. b. the 4 outer planets were found on the football field. c. most dwarf planets were located 2. Explain why was it impossible to place Sedna on the field? 3. Why do astronomers use the measurement of an AU instead of using km? 4. Describe something NEW that you learned from this activity.
