1916 Boreas a rotation period between 3.4741 and 3.49 hours with a brightness variation between 0.25 and 0.35 magnitude (). In 1994, astronomer Tom Gehrels estimated "Boreas" to measure 3.5 kilometers in diameter, based on an assumed albedo of 0.15. The "Collaborative Asteroid Lightcurve Link" assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 3.07 kilometers with an absolute magnitude of 14.93. This minor planet is named after the Greek god of the north wind, Boreas, as the asteroid was discovered moving rapidly northward after passing the ascending node of its orbit.
