Thanks to the Hubble Telescope, astronomers now have photographic proof that the North Star, formerly known as Polaris, has two stellar companions.The first, Polaris B, has been known since 1780 and can easily be seen with even a smaller telescope; the presence of the second, Polaris Ab, has been inferred but eluded direct detection because it was close to Polaris and relatively faint.
The North Star is a super-giant more than 2,000 times brighter than the sun, while its newly photographed second companion is a dwarf star just 2 billion miles from it, astronomers said.
that dot is a star? Sure it's not dust on the lens?
ReplyDeletewhich dwarf star is it, by the way? Sleepy? Doc?
