4 Vesta - Wikipedia
NASA's Dawn spacecraft entered orbit around Vesta on 16 July 2011 for a one-year exploration and left the orbit of Vesta on 5 September 2012 [33] en route to its final destination, Ceres. Researchers continue to examine data collected by Dawn for additional insights into the formation and history of Vesta.

2018年5月29日 · Vesta is the second most massive body in the asteroid belt, surpassed only by Ceres, which is classified as a dwarf planet. The brightest asteroid in the sky, Vesta is occasionally visible from...
Asteroid Vesta - Space Reference
Vesta is a dwarf planet orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Vesta as potentially hazardous because its orbit does not bring it close to Earth. Vesta orbits the sun every 1,330 days (3.64 years), coming as close as 2.15 AU and reaching as far as 2.57 AU from the sun.

2024年10月20日 · Vesta orbital period, the time it takes to complete an orbit of the Sun, is 3.63 years. The orbital inclination of Vesta, the angle at which Vesta orbits to the orbital plane, is 7.14079 degrees. The orbital eccentricity is 0.0884019 of Vesta, the degree at which Vesta orbits close to a circular (0) orbit as opposed to an elliptical (1).
Vesta - HyperPhysics
Its orbit places Vesta in the Main Asteriod Belt, but the object more closely resembles a small planet or Earth's Moon than another asteroid. "Unlike Ceres, which orbits just around or beyond the Solar System's ice line, Vesta's surface is not icy, …
