Scientists have announced the discovery of two new earth-like planets in our own galaxy so similar to our own that they have already fired into the top 20 contenders for future human colonization.
The planet orbits a neighbor star, Teegarden, only 12.5 light-years away in the Aries constellation. Teegarden is an ultralight dwarf star 10 times brighter than our own sun, eight billion years old and was discovered back in 2003.
"The two planets resemble the inner planets of our solar system," explains Mathias Zechmeister, an astrophysicist at Göttingen University and leading author of a study on the discovery.
"They are just a little heavier than the earth and are in the so-called habitable zone where water can occur in liquid form."
Teegarden b has a 60 percent chance of having a temperate surface environment suitable for housing thanks to temperatures from 0 to 50 degrees Celsius, with a likely average temperature of a soft 28 degrees. Given its mass and minimal radiation exposure, the Teegarden b, which completes its orbit in just 4.9 days, has made the highest earthquake index (ESI) ever.
Teegarden c would be closer in temperament to Mars, with a likely surface temperature of -47 degrees Celsius, so potential colonists may want a heavy jacket and some thick gloves. The Exoplanet completes its orbit in 11.4 Earth days.
"Both planets have a minimum mass near a soil mass, and [sic] a rocky, partial iron or water composition", wrote the team in their discoveries.
Do not pack your bags so far, as more research is needed to determine how viable future human housing of these exoplanets can be. One big problem is how quickly they orbit their rather weak star, which can make life there miserable or impossible.
