This illustration compares our Earth with the newly confirmed lava planet Kepler-78b. Kepler-78b is about 20 percent larger than Earth, with a diameter of 9,200 miles, and weighs roughly 1.8 times as ...
Researchers from MIT have located a lava-filled world about 700 light-years away that’s 40 times closer to its star than Mercury is to our sun. It’s considered one of the shortest orbital periods ...
This diagram illustrates the tight orbit of Kepler-78b, which orbits its star every 8.5 hours at a distance of less than a million miles. It is only 2.7 stellar radii from the center of the star, or 1 ...
