Gaia-DR2 will include:

  • Complete Astrometry (positions, proper motions and parallax angles) for 1,300 million stars (up to a magnitude of G= 21).
  • Radial velocity for more than 5 million stars (G betwen 3 and 12).
  • Magnitude G for 1,500 million stars.
  • Magnitude G_BP & G_Rp for 1,100 million stars.
  • Astrometric Data of 1,300 already-known asteroids.
  • Effective temperatures for 150 million stars (G<17).
  • More than 500,000 light curves of variable stars.


Gaia - DR2 is based on the observations made during 22 months (558 days), while for comparison, Gaia-DR1 compiled data of 14 months of observations.
