Eris (minor-planet designation: 136199 Eris) is the most massive and second-largest known dwarf planet in the Solar System. [22] It is a trans-Neptunian object (TNO) in the scattered disk and has a high-eccentricity orbit. Eris was discovered in January 2005 by a Palomar Observatory–based team led by Mike Brown and verified
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 ...
2005 – M. Brown, C. Trujillo, and D. Rabinowitz discover Eris, a TNO more massive than Pluto, [229] and later, by other team led by Brown, also its moon, Dysnomia. [230] Eris was first imaged in 2003, and is the most massive object discovered in the Solar System since Neptune's moon Triton in 1846.
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 ...
Mike Brown and his team discovered Eris a large body in the outer Solar System [25] which was temporarily named as (2003) UB 313. Initially, it appeared larger than Pluto and was called the tenth planet.
In 1801 Giuseppe Piazzi discovered Ceres, a body that filled the gap and was regarded as a new planet, [90] and in 1802 Heinrich Wilhelm Olbers discovered Pallas, at roughly the same distance to the Sun than Ceres. [91] He proposed that the two objects were the remnants of a destroyed planet, [92] and predicted that more of these pieces would ...
