Part 1: Motion of planets in our solar system * This is a plot of the enclosed mass for each planet in our solar system: Enclosed Mass (# x Mass_sun) 0 Value at the location of each planet * As you can see, the amount of mass that each planet orbits around is approximately the same no matter how far away it is from the sun. Any way you round it, 1.001 is still basically 1 * We know there are asteroids, moons, planets, and space debris (like meteoroids) between each planet and the sun. But all that mass is so tiny compared to the sun that it barely counts at all. * The mass that each planet rotates around is the same. The mass controlling the rotation of the solar system is 1.0 x the Mass of the Sun. Part 1: Motion of planets in our solar system * Make a plot of the orbital speed of each PLANET as a function of distance from the sun. * Plot or Graph, by drawing or on a tablet (but NOT with Excel) Mercury 50 km/s Venus 35 km/s 0.7 1.00000015 Earth 30 km/s 1 1.00000265 Mars 25 km/s 15 1.00000565 Jupiter 15 km/s 52 1.00000595 Saturn 10 km/s 10 1.00100595 Uranus 6 km/s 19 1.00125595 Neptune 5 km/s 30 1.00129960 & == = Q Q o un s | 5 | o Value at the location of each planet Q2: Using your orbital speed plot above, answer the question: How does the orbital speed change compared to the enclosed mass, as a function of distance? (example: When the mass enclosed the orbital speed of objects orbiting that mass with increasing distance from the center)
