- •
We observed Asteroid 2003 MS2 with radar with 19 m resolution.
- •
The dimensions of 2003 MS2 are 0.33 × 0.19 km.
- •
A circular polarization ratio of 0.30 is comparable to 25143 Itokawa suggesting a similar degree of near-surface roughness.
- •
The interval of orbit reliability increased with the radar and optical astrometry to 1564–2320.
