These 'failed stars' orbit so closely it took 29 years to tell they were a pair

[Admin]

The first and most famous "failed star" discovered by humanity isn't one brown dwarf, but two! The duo comprising Gliese 229B are so tightly bound they orbit each other in 12 days.

Wow! The illustration showing the size comparison is completely wrong! Jupiter is NOT half the diameter of the Sun, but closer to 1/10. So how big are the brown dwarfs in comparison?

Being an unbalanced rotation, after enough orbits, wouldn’t they end up where they began? Forming a larger longer orbit.

LoL Space Robot, good catch. Perhaps the map is not to scale

It is customary to make size comparisons to scale. This is further evidence, in my book, Robert Lea is AI. His postings, as with all other news writers on this site, are riddled with errors that a human astronomer would instantly fix, but an AI would not know to fix. The TOTALLY wrong size comparison speaks volumes. Can Mr. Lea appear here to defend the cause of his error? Was it ignorance, an oversight, what? Some kind of computer glitch maybe? How did it get in here? Why do we have to put up with this kind of stuff? Where are the fact checkers?

Used a NASA diagram for reference. Shame people got so hooked up on an image. Any errors are "human errors" showing I'm not a machine.

Thank you! Glad to hear it.

"This latter tool revealed the redshift of one brown dwarf, the "squashing" of wavelengths of light that indicates an object is moving away from Earth, and the blueshift of the other failed star, a stretching of the wavelength of light indicating movement toward Earth."

According to my information, from the observer's viewpoint, redshift is wavelength stretching, and blueshift is wavelength squashing.
