(704) Interamnia is an asteroid of the outer main asteroid belt , which was discovered on October 2, 1910 by Vincenzo Cerulli at his private observatory in Teramo ( Italy ). It was named after the ancient Roman name of Teramo, Interamnia .
Interamnia moves at a distance of 2.6 ( perihelion ) to 3.5 ( aphelion ) astronomical units in 5.35 years around the sun ; the orbital eccentricity is 0.15. At 17.3 °, the orbit is relatively strongly inclined towards the ecliptic .
With a diameter of around 306 km, Interamnia is the sixth largest object in the main belt. The asteroid has a dark carbon-rich surface with an albedo of 0.074. Observations have shown that the surface is unusual, possibly dust-free. Interamnia rotates around its own axis in around 8 hours and 44 minutes.
