Managing Partner and Creative Director at Lockhart Media + Marketing. Founder of Sci Fi Generation TV. More on that some other time.
Focus, while I display flows ferocious about science, technology, creativity, and innovation. I'm very interested in how all of the above impact culture and society. I believe that the most scientifically literate among us will move society forward at a speed we've never seen before. I also believe that the most creative among us will make that trip forward a fun one. This is my personal blog, filled with wondrous things from across the Universe, which will hopefully inspire you to go change the world, or at least, your seat.
Of all the stars closer than 15 light-years, only two are spectral type G, similar to our sun: Alpha Centauri A and Tau Ceti. The majority are M-type red dwarf stars.
Only nine of the stars in this area are bright enough to be seen by the naked human eye from Earth. These brightest stars include Alpha Centauri A and B, Sirius A, Epsilon Eridani, Procyon, 61 Cygni A and B, Epsilon Indi A and Tau Ceti.
Barnard’s Star, a red dwarf 5.96 light-years away, has the largest proper motion of any known star. This means that Barnard’s Star moves rapidly against the background of more distant stars, at a rate of 10.3 seconds of arc per Earth year.
Sirius A is the brightest star in Earth’s night sky, due to its intrinsic brightness and its proximity to us. Sirius B, a white dwarf star, is smaller than Earth but has a mass 98 percent that of our sun.
In late 2012, astronomers discovered that Tau Ceti may host five planets including one within the star’s habitable zone. Tau Ceti is the nearest single G-type star like our sun (although the Alpha Centauri triple-star system also hosts a G-type star and is much closer).
The masses of Tau Ceti’s planets range from between two and six times the mass of Earth.
