Vesta is thought to be the second-largest asteroid, both by mass and by volume, after the dwarf planet Ceres. [ 20 ] [ 21 ] [ 22 ] Measurements give it a nominal volume only slightly larger than that of Pallas (about 5% greater), but it is 25% to 30% more massive.
The largest asteroids with an accurately measured mass, because they have been studied by the probe Dawn, are 1 Ceres with a mass of (939.3±0.5)×1018kg, and 4 Vesta at (259.076±0.001)×1018kg. The third-largest asteroid with an accurately measured mass, because it has moons, is 87 Sylvia at (14.76±0.06)×1018kg.

2 dni temu · Vesta, second largest—and the brightest—asteroid of the asteroid belt and the fourth such object to be discovered, by the German astronomer and physician Wilhelm Olbers on March 29, 1807. It is named for the ancient Roman goddess of the hearth (the Greek Hestia).
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 ...
