If you think living on Earth can be challenging, try spending a day on 55 Cancri e. The "super earth," is located about 40 light years from here, and at least half of it is likely covered in blazing hot lava. <br /> <br /> <br />If you think living on Earth can be challenging, try spending a day on 55 Cancri e. <br />The "super earth," is located about 40 light years from here, and at least half of it is likely covered in blazing hot lava. <br />Temperatures can hover upwards of 4,400 degrees Fahrenheit. <br />Part of the heat problem is due to the exoplanet’s incredibly close proximity to its sun. <br />The issue is particularly pronounced on one side of the celestial body as astronomers believe it is tidally locked to the star, much like our moon is to Earth.
