A ‘super-Earth’ may have been discovered just six light years away
Just six light-years away, a frozen world seems to be orbiting a small, dim red star https://on.natgeo.com/2B6gUGZ s
An exciting planet candidate - a cold super-Earth - was announced today by a raft of #exoplaneteers including twitterati @johannateske, @astrojennb, and more, orbiting one of the closest stars to us - a nearby, fast-moving red star called Barnard's star!https://xkcd.com/2062/
A frozen super-Earth may orbit Barnard’s Star. At just six light years away, the candidate planet would be the second-closest world known beyond our solar system—and a prime target for future studies. http://bit.ly/2PqaRG6 (By @LeeBillings)pic.twitter.com/mfALmFlusO
In the not-so-distant someday when telescopes become capable of photographing planets around other stars, this may well be the first new world we see.https://www.washingtonpost.com/science/2018/11/14/signs-super-earth-discovered-around-nearby-star/?utm_term=.ce16b0699c86 …
Meet Barnard's Star b: It's 3.2 times as massive as Earth, has a year of 233 days and a surface temperature of around -170°C (-274°F). It's also the closest exoplanet ever found in a single star system.https://motherboard.vice.com/en_us/article/d3bpzz/scientists-discover-super-earth-six-light-years-barnards-star-b …
An international team including five @CarnegiePlanets & @CarnegieAstro astronomers analyzed 20 years of data to discover a frozen Super-Earth orbiting Barnard’s star, the closest single star to our own Sun. https://carnegiescience.edu/news/cold-super-earth-found-orbiting-second-closest-star-system-our-own …pic.twitter.com/zBWCFeS1a6

At last, a planet for Barnard's Star! COOL! http://bit.ly/2Fihrd0 It's the 2nd closest star system to our sun, at 6 light-years away. Astronomers are "99 percent confident" that this exoplanet is real and not a false detection. It appears to be a cold super-Earth.pic.twitter.com/W3pS1ktSqu
I can see the real estate brochure: "Just 4 light years from major shopping; close to interstellar routes of choice; only a galaxy to great beaches...."
That's approximately 35.28 trillion miles by the way. Who's gonna pay for gas?
"Only" 6 light years away?! Well, let's leave now
maybe Super Earth will be forced to eat Normal Earth and that's how this whole thing will endhttps://twitter.com/washingtonpost/status/1062804755473408001 …
