Earth's evil exoplanet twin
This is a follow-up to my previous post.
Big Island News posted a rather long albeit interesting article about an exoplanet called "Gliese 12 b", about 40 light years away. The research team used NASA’s Transiting Exoplanet Survey Satellite and three Mauna Kea observatories, Keck, Gemini, and Subaru, to nail down the size and mass of a rocky exoplanet. The planet is Earth-sized; in fact, they narrowed it down to Venus-sized, which is only a tiny bit smaller than Earth. It's in a very different solar system; it orbits a red dwarf, a star much cooler than our sun, and a year on that planet lasts just over 12 days. But it's in a region where liquid water should exist and likely has an atmosphere that is not particularly pleasant for humans.
"The researchers think the newly discovered exoplanet is an “evil twin” because of the data they’ve gotten so far making it look more like Venus than Earth".
