List of stars closer than 20 light years

Science Fiction writers often need the name of a nearby star. This list includes most of the stars within 20 light years of Sol. If you are looking for sun type stars look for Spectral type G with an absolute magnitude of 3 to 5.

Many stars are actually double stars, so both stars are listed with the same name. Sometimes a little star orbits a big star like a planet, these might be super Jupiters with enough mass to start nuclear fussion. Sometimes they are just two stars with a large distance between them that lazily circle around each other. Sometimes they are stars that met in space and somehow wound up together.

The brighter the star, the smaller it’s magnitude. The brightest stars have negative magnitudes. Sirius – the dog star – is close by and is very bright. As seen from the earth it has an apparent magnitude of -1.46 making it on of the brightest things in the sky. Most of these stars are not as bright as the sun. They are (on the average) between 4 and 5 light years apart.

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.

Playing "Help-Me" In the Style of Sonny Boy Williamson II: A step by step, note for note analysis of some of Sonny Boy's Signature Riffs

I also write Science Fiction, so you can sample some of my best stories. Also available in Kindle format.

I started reading Science Fiction in the 1950s. I started Writing SF in the 1960s. Then, I had a life. Now I am retired, raising chickens and keeping bees. I am still an avid reader and I have sold about 70 stories in the last 20 years.
I have been collecting information about writing Science Fiction for many years now. Social media has replaced the Blog and large dedicated websites, so the pages here are mostly static. I update them from time to time.

Enjoy!
