Right Ascension vs. Declination

did you know...? May 01, 2021

Right Ascension and Declination are the types of celestial coordinates that astronomers use to map the sky. They are similar to latitude and longitude coordinates that are used for locations on Earth.

  • Right Ascension (RA) - comparable to LONGITUDE. Measures east/west coordinates
  • Declination (Dec) - comparable to LATITUDE. Measures north/south coordinates

Every star has a designated Right Ascension and Declination.  These coordinates are used to study specific areas in the sky.
