Figure Your Weight on Other Planets
Mass x Gravity = Weight
To find your weight on other planets, you first need to find your mass. Then, multiply your mass by the force of gravity on other planets to find your weight on those planets. These tables should help, but keep in mind that the numbers are approximations based on scientific theory.
Note that you must first find your weight in Newtons.
_____ pounds x 21.6 = _____ Newtons
Your weight on Earth (Newtons) 
divided by  Gravity on Earth (meters per second^{2}) 
=  Your mass (kilograms) 
divided by  9.8  = 
Your mass (kilograms) 
x  Gravity on another planet (meters per second^{2}) 
=  Your weight on another planet (Newtons) 

Mercury  x  3.7  =  
Venus  x  8.87  =  
Mars  x  3.69  =  
Jupiter  x  23.12  =  
Saturn  x  8.96  =  
Uranus  x  8.69  =  
Neptune  x  11.0  =  
Pluto  x  0.66  = 
Figure Your Age on Other Planets
There are two approaches to figuring your age. The first calculates the number of Earth years it takes to reach your current Earth age on the other planet. The second calculates your current Earth age in terms of the other planet's years. Try figuring your age both ways, but keep in mind that these numbers are approximations based on scientific theory.
Age in Earth years  x  # of Earth years  =  Age on another planet  
Mercury  x  0.24  =  
Venus  x  0.62  =  
Mars  x  1.88  =  
Jupiter  x  12  =  
Saturn  x  29.5  =  
Uranus  x  84  =  
Neptune  x  165  =  
Pluto  x  248  = 
Age in Earth years  divided by  # of Earth years  =  Age on another planet  
Mercury  divided by  0.24  =  
Venus  divided by  0.62  =  
Mars  divided by  1.88  =  
Jupiter  divided by  12  =  
Saturn  divided by  29.5  =  
Uranus  divided by  84  =  
Neptune  divided by  165  =  
Pluto  divided by  248  = 
Imagine what it would be like to really visit the other planets. What would it feel like in different gravity? How would the climate be? What might the lifeforms look like? If you're interested, take a look at "An Inquirer's Guide to The Universe" for outer space activities.
