Good news and bad news.
Good news first. Scientists have found a couple more Earth-like planets!
Bad news. They’re eleven light years away. One light year is the equivalent of six trillion miles. So do the math. These planets aren’t exactly around the block. There goes our quest for space colonization. Boo.
From the New York Post:
A team of German astronomers has discovered two super-Earths near the red dwarf star Gliese 887 and just a short 11 light-years away from Earth.
Super-Earths are planets with a mass greater than Earth’s, but less than those of the ice giants Uranus and Neptune. The two exoplanets — planets located outside of our solar system — were named Gliese 887b and Gliese 887c, respectively.
Using a technique called the “Doppler wobble,” they found the planets to have orbits of just 9.3 and 21.8 days — faster than Mercury’s highly elliptical 88-day orbit.
Gliese 887b and Gliese 887c are located near their star’s habitable zone, an area where liquid water may potentially exist. That said, measurements of Gliese 887c suggest a surface temperature of 158 degrees Fahrenheit or 70 degrees Celsius.
