19 Fortuna is one of the biggest main belt asteroids. It is made up of stuff similar to 1 Ceres: a darkly colored surface that is heavily space weathered and made up of primitive organic compounds, including tholins.
Fortuna is 225 km in diameter and has one of the darkest known geometric albedos for an asteroid over 150 km in diameter. Its albedo has been measured at 0.028 and 0.037.
The Hubble Space Telescope saw Fortuna in 1993. It was resolved with an apparent diameter of 0.20 arcseconds (4.5 pixels in the Planetary Camera) and its shape was found to be nearly spherical. Moons were searched for but none were detected.
