Diagrams: ' My Weight Throughout the Solar System ' Estimated weight on Earth: __________ lbs. Location in Solar System Planets: Dwarf Planets: Mercury Mass/Gravity Compared to Earth 0.90 Jupiter 2.5 Saturn 1.10 Ceres 0.00016 Pluto 0.04 Moons: Earth’s Moon 0.17 Stars: The Sun Insert your weight onto the line (or choose whatever weight you want to use). 0.40 Venus Mar’s Moon Phobos My weight at this location would be: 0.0006 28.0 Multiply the weight by the figure given for each object. Round to the nearest whole number. If an object weighs less than one pound, use the “less than” symbol (>), Weight Just a Minute! Many people think that the terms “mass” and “weight” mean the same thing, but they don’t. Mass is a measurement of the amount of matter that an object contains, while weight is a measurement of the pull of gravity upon an object. Unlike mass, which doesn’t change, an object’s weight can change depending on its location. For example, on the moon you would weigh about one sixth of your weight here on Earth. This is because the moon is much less massive than Earth, so the pull of the moon’s gravity would be far less than that of Earth’s gravity. If you should travel to another planet, moon, or star, your weight would change again, depending on the mass and amount of gravitational pull present at each location.
