Due to the distant and eccentric orbit of Eris, its surface temperature is estimated to vary from about 30 to 56 K (−243.2 to −217.2 °C; −405.7 to −358.9 °F). [2] Even though Eris can be up to three times farther from the Sun than Pluto, it approaches close enough that some of the ices on the surface might warm enough to sublime to ...

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 ...
Mars is the only other planet to have had its surface explored by a mobile surface probe (rover). Titan is the only non-planetary object of planetary mass to have been explored by lander. Landers have explored several smaller bodies including 433 Eros (2001), 25143 Itokawa (2005), Tempel 1 (2005), 67P/Churyumov–Gerasimenko (2014), 162173 ...
2018 AG 37 was first imaged on 15 January 2018 by astronomers Scott Sheppard, David Tholen, and Chad Trujillo when they were surveying the sky using the large 8.2-meter Subaru Telescope at Mauna Kea Observatory, Hawaii, to find distant Solar System objects and the hypothetical Planet Nine, whose existence they proposed in 2014.
Combined with its high orbital eccentricity, the planet's surface has widely varying sunlight intensity and temperature, with the equatorial regions ranging from −170 °C (−270 °F) at night to 420 °C (790 °F) during sunlight. Due to the very small axial tilt, the planet's poles are permanently shadowed.
The dwarf planet systems Pluto–Charon and Eris–Dysnomia are the only known examples of mutual tidal locking in the Solar System, [21] though it is likely that Orcus–Vanth is another. [ 22 ] The reddish-brown cap of the north pole of Charon is composed of tholins , organic macromolecules that may be essential ingredients of life .
