They orbit outside Jupiter's ring about 80,000 miles from Jupiter's center in 7 hours, and are probably less than 40 km in diameter. A reddish, irregular body about 140 by 265 km.
Red coating is sulfur escaping from Io.
Fuzzy images were obtained that indicate some large craters and bright spots. Little is known otherwise. Orbital radius 113,000 miles. Revolves around Jupiter in 12 hours. It is about 30 miles in diameter.
