    213 Lilaea is a large main belt asteroid. It was discovered by German-American astronomer C. H. F. Peters on February 16, 1880, in Clinton, New York and was named after Lilaea, a Naiad in Greek mythology.

    Photometric observations of this asteroid in 1986 gave a light curve with a period of 8.045 ± 0.008 hours and a brightness variation of 0.20 ± 0.01 in magnitude. The curve is asymmetrical with two distinct minima. This object has a spectrum that matches an F-type asteroid classification. [3] As with C-type asteroids, its composition is primitive and rich in carbon.
