Red Dwarf Characteristics
Red dwarfs are the smallest, coolest, and most common type of star. Estimates of their abundance range from 70% to more than 90% of all stars in elliptical galaxies, an often quoted median figure being 73%. Red dwarfs are either late K or M spectral type. Given their low energy output, red dwarfs are never visible by the unaided eye from Earth; neither the closest red dwarf star to the Sun when viewed individually, Proxima Centauri (which is also the closest star to the Sun), nor the closest solitary red dwarf, Barnard's star, is anywhere near visual magnitude.

Famous quotes containing the words red and/or dwarf:
“He was as bald as a hump.
His ears stuck out like teacups
and his tongue, my God, his tongue,
like a red worm and when he kissed
it crawled right in.”
—Anne Sexton (19281974)
“When I lie down to love,
old dwarf heart shakes her head.
Like an imbecile she was born old.”
—Anne Sexton (19281974)
