Earth worth $3 quadrillion

An astrophysicist, who created a formula to calculate the value of planet Earth, has claimed that Earth is worth three thousand trillion pounds.
Greg Laughlin came up with the figure by calculating the sum of the planet’s age, size, temperature, mass and other vital statistics-and Earth came out as the most expensive, reports the Daily Mail.
Mars was only valued at £10,000. Venus is said to be worth less than a penny.
There are about 1,235 other planets in the universe, most of which weren’t given a high price tag because of their inhospitable climates.
Laughlin from the University of California-Santa Cruz invented the equation, which he used to evaluate the discoveries made by NASA’s 600 million pound Kepler spacecraft.
The planet-hunting spacecraft went into orbit two years ago and a year later Laughlin decided to create price tags for the terrestrial planets that Keplar was to discover.
He said only planets worth more than 60 million pounds were probably worth extensive study.
“The formula makes you realise just how precious Earth is and I hope it will help us as a society safeguard what we have,” he said.
At the time, the exoplanet Gilese 581 c was considered the most Earth-like world known to scientists, but the equation only valued it at £100, while KOI 326.01 is said to be worth £150,000. (With PTI inputs)
