How Much Is That Planet Worth?

Suppose, for a minute, you were on your way to go shopping when a guy, who turns out to be a tout, catches your attention. Here's their part of the conversation that follows....

Hey, bud... c'mere a minute. What are you doing? Shopping? Nah, you don't wanna do that. Not big enough for you. Hey, you wanna get in on buying a planet?

Now, you've probably never considered buying your own planet before, but sure, why not?

At this point, it would probably be a really good idea to know how much any planet you might consider buying might be worth, so you can know what a good deal might be and so you can avoid getting taken to the cleaners, don't you think?

Fortunately for you, our latest tool is here to help! Based on math developed by astrophysicist Greg Laughlin (HT: boingboing), our tool can give you a really good idea at what the economic value of any planet you might consider buying might be worth!

All you need to know is the planet's mass, its estimated temperature, and the age, type and apparent brightness of its star. Enter that relevant data into our tool and soon you'll know just how much that planet you're thinking about buying is really worth!

We've entered the default data for Earth and the Sun (mass, age) into the tool, but you're certainly welcome to substitute the world of your choice, whether in Earth's local neighborhood, or elsewhere!

Planet Data
Input Data Values
Effective Black Body Temperature of the Planet [degrees Kelvin]
Mass of the Planet [quadrillion (1024) kg]
Year of Discovery [Enter 2009 if Discovered Prior to 2009]
Age of the Planet's Star [billion years]
Mass of the Planet's Star [quintillion (1030) kg]
Apparent Visual Magnitude (Brightness) of the Planet's Star


Value of the Planet
Calculated Results Values
Estimated Value [Constant 2009 U.S. Dollars]

Because really, the worst thing that can happen is that you're out your money and stuck owning a planet that isn't worth as much as you might have thought it would be!

But we'll close by cautioning our readers to avoid buying any planets whose existence so far is only hypothetical!

Update 6:33 AM: Coding glitch corrected - now up and running!
