Frozen super-Earth discovered six light-years away
CNN ^ | November 14, 2018 | Ashley Strickland,

The red dwarf star itself emits only about 0.4% of our sun's radiance, so the planet receives about 2% of the intensity that Earth receives from its sun. This is because Barnard's star is in the class of M dwarf stars, cooler and less massive than our sun. It's also an old star that predates our own solar system.

The planet is about the same orbital distance from its star as Mercury is from our sun, making a full pass around the star every 233 days. This places it in the "snow line" of the star, where it's cold enough for water to freeze into solid ice. This region in a planetary system is where the building blocks of planets are thought to form, collecting material to become cores. As they migrate closer to their host stars, gathering more material, they become planets.

It's the first time a planet this small and distant from its star has been detected using the radial velocity technique, which Butler helped pioneer. This method is sensitive to the mass of the exoplanet and measures changes in the host star's velocity. Instruments can be used to detect tiny wobbles in the star's orbit that are caused by the planet's gravity.

In the 1930s, Dutch-American astronomer Peter van de Kamp began a quest to study Barnard's star that lasted for most of his 93 years. His claims of how planets could fit in orbit around the star were refuted...

...

And it will still be shining long after the Sun is burned out.

Red dwarfs stay in their main sequence for trillions of years.

Hell, 6 light years may as well be right down the street.

I am of the opinion that it would be easier to heat a cold planet via solar reflectors than to cool a hot planet. Either way, habitation if possible would require some terraforming.

Less than 2 parsecs!

New Horizons travels at around 36,373 mph. One light-year is 5.87849981 × 10 12 miles. (That’s 5,878,499,810,000 miles, or nearly 6 trillion miles). So, it would take New Horizons 18,449 years to travel one light year.

Times 6.

If it still has a magnetic field, molten core and some atmosphere it is possible, just a lot of hard work.

Providing the level of toxins are not too high.

Did CNN actually stumble on a "global warming" factoid there with regard to solar activity. They won't even realize it. The volume of koolaid they've consumed blinds them to it.

Lemme know when the scientists get a short signal indicating the numbers —> 3.1415 etc etc etc

That’ll be the DAY !!!

Exactly! In galactic terms, right down the street. If we left now, we could be there in 110,694 years or so.

It’s not an Earth, and it’s not a Super-Earth either. And forget about going there. In other words, why this article?
