[1]London: 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, pounds while 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 pounds 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 set to discover.
The older the star, the more value it has because it has had the chance to mature, the mass is then taken into account and generally if it’s around the same size as Earth it is thought of as a good size for supporting life.
Laughlin also took into account the amount of energy the star creates and whether its temperatures could also support life.
“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.
