We commonly have the idea that the large bodies of the Solar System, called planets, dwarf planets and asteroids of considerable size, terminate in the orbit of Pluto, and beyond that (Kuiper Belt) are only small debris that never came to form structures Solids. But this idea is erroneous, since beyond Pluto there are still many bodies that deserve to be studied. A great example of this is ERIS, a dwarf planet with a mass 27% higher than that of Pluto and a diameter of approximately 2320 kilometers. It has a highly elliptical orbit, that is, its point closest to the Sun and its farthest point are very different from each other, besides being fairly inclined in relation to the plane of the ecliptic (the imaginary plane in which all move The planets around the Sun. It is estimated that due to its great distance from our star, Eris's orbit is completed in approximately 557 YEARS. It is so far from the Sun that at certain point in its orbit its atmosphere would freeze and fall on The surface as a fine enamel that adds shine to the dwarf planet, which is why scientists believe that surface temperatures range from a pleasant -217 to -243 degrees Celsius.

Erís also has a natural satellite called DISNOMIA of just 350 kilometers in diameter and that orbits Eris at a distance of approximately 37 370 kilometers. The observations of this dwarf planet and its satellite were possible thanks to the telescopes Hubble (in orbit) and Keck (in ground).
