Introduction

One earth year is calculated based on the time it takes to complete one revolution around the sun. Other planets take a different amount of time to complete one revolution.

How old are you in another planet's years?

Planet	Revolution Period in Earth Days/Years
Mercury	87.97 days
Venus	224.7 days
Earth	1 year (365.26 days)
Mars	1.88 years
Jupiter	11.86 years
Saturn	29.46 years
Uranus	84.01 years
Neptune	164.79 years
Pluto	248.59 years

Project #1

Write an interactive program that

1. ask a person's age in years
2. displays the person's approximate age on different planets
3. Loop

To display the data in a "nice table/format" use F strings or the tabulate module.

Project #2

Write a program similar to the one in project #1. Calculate how much would you weigh on another planet.

To find out how much you would weigh, multiple your weight on Earth by the g-factor in the table below.

The easiest way to discuss the gravitational force on other planets is to express it as a fraction of Earth's g-force.

The following are the g-forces (gravity) you would experience on another planets if you were standing on the surface or, in the case of the ice giants, floating in the atmosphere.

Planet	Fraction of Earth's g-force
Mercury	0.38 g
Venus	0.9 g
Earth	1 g
Moon	0.17 g
Mars	0.38 g
Jupiter	2.53 g
Saturn	1.07 g
Uranus	0.89 g
Neptune	1.14 g
