Scientists have discovered an exoplanet named GJ 1132b, which is Earth-sized and rocky, orbiting a small star located just 39 light-years from Earth. But you wouldn’t want to live there.
Scientists have discovered a new exoplanet that, in the language of “Star Wars,” would be the polar opposite of frigid Hoth, and even more inhospitable than the deserts of Tatooine. But instead of residing in a galaxy far, far away, this new world is, galactically speaking, practically next door.
The new planet, named GJ 1132b, is Earth-sized and rocky, orbiting a small star located a mere 39 light-years from Earth, making it the closest Earth-sized exoplanet yet discovered.
Based on their measurements, the scientists have determined that the planet is a roasting 500° F (260° C), and it is likely tidally locked, meaning that it has a permanent day and night side — presenting the same face to its star, much like our Moon is locked to Earth.
Because of its scorching temperatures, GJ 1132b most likely cannot retain liquid water on its surface, making it uninhabitable for life as we know it. However, scientists say it is cool enough to host a substantial atmosphere.
The planet is also close enough to Earth that scientists may soon be able to find out much more about its characteristics, from the composition of its atmosphere to the pattern of its winds — and even the color of its sunsets.
