Named the Asteroidal Gravity Optical and Radar Analysis (AGORA), this spacecraft was to launch some time in 1990–1994 and perform two flybys of large asteroids. The preferred target for this mission was Vesta.
4 Vesta — the second-largest asteroid in the solar system at 525 km (326 miles) in size and is also located in the asteroid belt between Mars and Jupiter. It contributes about 9% of the total mass of the entire belt. It has an orbital time of 3.63 years and it has an axial tilt of 29 degrees.

Vesta is the second most massive body in the main asteroid belt, accounting for almost 9% of the total mass of all asteroids. Only dwarf planet Ceres is more massive in that region of rocky debris between Mars and Jupiter.
Pallas (minor-planet designation: 2 Pallas) is the third-largest asteroid in the Solar System by volume and mass. It is the second asteroid to have been discovered, after Ceres, and is likely a remnant protoplanet.
Vesta is the second most massive object in the asteroid belt (after Ceres) with a mass of 2.59 x 10 20 kg. However, in terms of size, it ranks as number three in the asteroid belt (after Ceres and Pallas), with a mean diameter of 525 km. Seen from Earth, Vesta is the brightest of the asteroids; at its brightest it can just barely be seen with ...
