The planets orbit the host star in synchronized rhythms of orbital resonance (a rare 1 percent of such systems in the Milky Way galaxy have this symmetry): the innermost planet orbits three times for every two times for the next planet out – a so-called 3:2 resonance; this same 3:2 resonance also applies to the second and third planet, as ...
This gave an isophotal diameter for the Milky Way at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years), by assuming that the galactic disc is well represented by an exponential disc and adopting a central surface brightness of the galaxy (μ 0) of 22.1 ± 0.3 B-mag/arcsec −2 and a disk scale length (h) of 5.0 ± 0.5 kpc (16,300 ± 1,600 ly).

In astronomy, the Great Rift (sometimes called the Dark Rift or less commonly the Dark River) is a dark band caused by interstellar clouds of cosmic dust that significantly obscure ( extinguish) the center and most radial sectors of the Milky Way galaxy from Earth 's perspective. In dark, clear night skies, the rift appears as clear as the ...
