Age in Mars Years

Find out how old you are in Mars years or the years of other planets.

Run the code to find the orbit period of Mars. Try other planets, like Venus or Neptune:

Use plain English to get an exact representation of the planet Mars. Type += and in the input box, type “mars”:

An exact representation gives you access to all sorts of information about the planet—for example, the period of its orbit (how long it takes to go once around the Sun, which is the length of one of the planet’s years).

A Mars year is 1.88 Earth years:

You can make this expression easy to apply to any planet by turning it into a pure function:

To make a pure function, replace with # and follow the expression with &:

DateDifference["Jan 2, 1999", Today] /#["OrbitPeriod"] &

You can use that expression to find an age in the years of any planet:

This gives you a list of all of the planets:

PlanetData[]

Find your age in the years of all of the planets:

DateDifference["Jan 2, 1999", Today] /#["OrbitPeriod"] & /@ PlanetData[]

Add the planet to the age:

{#, DateDifference["Jan 2, 1999", Today] /#["OrbitPeriod"]} & /@ PlanetData[]

Format the data as a grid:

Grid[{#, DateDifference["Jan 2, 1999", Today] /#["OrbitPeriod"]} & /@ PlanetData[]]

Label the columns:

Deploy the planetary age calculation to make a website where you can enter a birthdate and find out how old you are in years of all the planets. With[{date=#birthdate}, ...] is necessary so that it is clear that the #birthdate parameter belongs to the outer pure function (the one that CloudDeploy is acting on) and not the inner one (the one mapped over PlanetData[]):
