382 Dodona is a large Main belt asteroid that was discovered by the French astronomer Auguste Charlois on January 29, 1894 in Nice. It is classified as an M-type asteroid.

Measurements of the thermal inertia of 115 Thyra give an estimated range of 15–150 J m−2 K−1 s−1/2, compared to 50 for lunar regolith and 400 for coarse sand in an atmosphere.[2]
