The objects, left to right are: 1 dwarf planet Ceres, 2 Pallas, 3 Juno, 4 Vesta, 5 Astraea, 6 Hebe, 7 Iris, 8 Flora, 9 Metis, and 10 Hygiea. The scale is 10 km/px on the original image, though not necessarily on the repro here.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Both Vesta and Pallas have assumed the title of second-largest asteroid from time to time. [47] At 513 ± 3 km in diameter, [ 9 ] Pallas is slightly smaller than Vesta ( 525.4 ± 0.2 km [ 48 ] ). The mass of Pallas is 79% ± 1% that of Vesta, 22% that of Ceres, and a quarter of one percent that of the Moon .
At most oppositions, however, Juno only reaches a magnitude of around +8.7 [24] —only just visible with binoculars—and at smaller elongations a 3-inch (76 mm) telescope will be required to resolve it. [25] It is the main body in the Juno family. Juno was originally considered a planet, along with 1 Ceres, 2 Pallas, and 4 Vesta. [26]

The asteroids were initially named from mythology as well—Ceres, Juno, and Vesta are major Roman goddesses, and Pallas is an epithet of the major Greek goddess Athena—but as more and more were discovered, they first started being named after more minor goddesses, and the mythological restriction was dropped starting from the twentieth ...
The next largest are 4 Vesta and 2 Pallas, both with diameters of just over 500 km (300 mi). Vesta is the brightest of the four main-belt asteroids that can, on occasion, be visible to the naked eye. [70] On some rare occasions, a near-Earth asteroid may briefly become visible without technical aid; see 99942 Apophis.
