other in darkness. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. Moving perpendicular to the galactic plane at a fast velocity of 47 km/sec, Lalande 21185 appears to belong to the our Milky Way galaxy's "thick disk," which has a mean thickness of 3,500 ly.
