Eris has been measured at 2,326 ± 12 kilometres (1,445 ± 7 mi) in diameter; [12] its mass is 0.28% that of the Earth and 27% greater than that of Pluto, [23] [24] although Pluto is slightly larger by volume. [25] Both Eris and Pluto have a surface area that is comparable to that of Russia or South America. Eris has one large known moon, Dysnomia.
Dwarf planet Eris, similar in size to its better-known cosmic cousin Pluto, has remained an enigma since being discovered in 2005 lurking in the solar system's far reaches. While Pluto was ...
Vesta (radius 262.7 ± 0.1 km), the second-largest asteroid, appears to have a differentiated interior and therefore likely was once a dwarf planet, but it is no longer very round today. [74] Pallas (radius 255.5 ± 2 km ), the third-largest asteroid, appears never to have completed differentiation and likewise has an irregular shape.
For example, if a TNO is incorrectly assumed to have a mass of 3.59 × 10 20 kg based on a radius of 350 km with a density of 2 g/cm 3 but is later discovered to have a radius of only 175 km with a density of 0.5 g/cm 3, its true mass would be only 1.12 × 10 19 kg.
Eris (13 cm (5.1 in) in diameter) is located at Umeå Arts Campus, Umeå, 518 km (322 mi) from the Globe. Made by Theresa Berg , the golden model is inspired by the mythical story of Eris sparking a quarrel between three Greek goddesses with a golden apple bearing the inscription καλλίστῃ ( kallistē , "to the most beautiful one").
The flyby of Earth reduced Juice’s speed by 10,737 miles per hour (4.8 kilometers per second) to set it on the path toward Venus and will save the mission around 220 to 330 pounds (100 to 150 ...

524522 Zoozve (/ ˈ z uː z v eɪ / ⓘ; provisional designation 2002 VE 68) is a sub-kilometer sized asteroid and temporary quasi-satellite of Venus. [5] Discovered in 2002, it was the first such object to be discovered around a major planet in the Solar System.
