1565 Lemaître, provisional designation 1948 WA, is a highly eccentric Phocaea
Mars-crosser from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 25 November 1948, by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle, Belgium.[3] It was named after cosmologist and priest Georges Lemaître.[2]

Physical characteristics
In the
SMASS taxonomy, Lemaître is characterized as a Sq-type, a transitional class of stony S-type and Q-type asteroids.[1]

Diameter and albedo
According to the surveys carried out by the Japanese
albedo between 0.22 and 0.334.[6][7][8] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for Phocaea asteroids of 0.23 – derived from 25 Phocaea, the family's most massiv member and namesake – and calculates a diameter of 8.76 kilometers based on an absolute magnitude of 12.5.[4]
