It was discovered on 24 May 1927, by Catalan astronomer Josep Comas i Solà at the Fabra Observatory in Barcelona, Spain, who named it after his niece.

[2][1] The bright S-type asteroid has a notably short rotation period of 2.9 hours and measures approximately 10 kilometers (6.2 miles) in diameter.

Reginita is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.

[12][13][14][15][16][17] The consolidated lightcurve analysis gave a rotation period of 2.946 hours with a brightness amplitude between 0.10 and 0.33 magnitude (U=3).

[6][7][8][10][11] The Collaborative Asteroid Lightcurve Link adopts Petr Pravec's revised WISE data, that is, an albedo of 0.3516 and a diameter of 10.29 kilometers based on an absolute magnitude of 11.69.
