If the value is positive, it is north of the celestial equator. And that has allowed us to do something that had never been accomplished before to see the nearest stars visibly displaced on the sky from the positions we see them on Earth, said Alan Stern, New Horizons principal investigator from Southwest Research Institute (SwRI) in Boulder, Colorado, in a statement. stated in. Previous searches using ground-based, photographic astrometry . They are, and they could be a reality in astronomy exploration very soon. Lalande 21185 is the brightest red dwarf in the northern sky, but still invisible to the unaided eye with an apparent magnitude of 7.520. In 1995, observations with the Hubble Space Telescope revealed 32 flare-like events over a period of 2 hours. Conversion: 5.8786x . [34] No excess infrared emission has been detected, which may indicate the lack of a debris disk in orbit around it. Its variable star designation is CN Leonis. These are equivalent to the Longitude and Latitude on Earth.
