Eris (dwarf planet) The orbit of Eris. Eris is a dwarf planet and a trans-Neptunian object (TNO). Eris is the second-largest dwarf planet known in the Solar System. It is a scattered disc object and it is in the Kuiper belt, farther out than Pluto. It is also called a plutoid because the IAU decided to rename all trans-Neptunian dwarf planets as plutoids.

The Dwarf Planet Sedna In the meantime, the category has been used tentatively to describe many Trans-Neptunian objects that were discovered before or since the discovery of Eris. Sedna, which was discovered in the outer reaches of the Solar System in 2003, is most likely a dwarf planet.edna has a highly elliptical orbit around the Sun, which means it ranges in distance from 76 astronomical units (AU) at perihelion (114 billion km/71 billion mi) to 936 AU (1,400 billion km/870 billion mi) at aphelion.

How far is Eris from the Sun ? The dwarf planet Eris is in a highly elliptical orbit (elliptical = oval-shaped) with an perihelion (closest point to the Sun) of 38 AU, and an aphelion (farthest point from the Sun) of 97 AU. Currently, Eris is near its farthest point from the Sun, about 96.7 AU (9 billion miles or 14 billion kilometers) from the Sun.

Ceres (dwarf planet) The 2006 IAU decision that classified Ceres as a dwarf planet never addressed whether it is or is not an asteroid. Indeed, the IAU has never defined the word 'asteroid' at all, having preferred the term 'minor planet' until 2006, and preferring the terms 'small Solar System body' and 'dwarf planet' after 2006.

- Dwarf Planet Ceres. Ceres was named after the Roman goddess of the harvest, of growing plants, and motherly love. It is the smallest of the dwarf planets, a new category of astronomical bodies created by the International Astronomical Union in 2006. Dwarf planets currently includes Pluto, Eris, and Ceres..

- Dwarf planets also are generally smaller than the planet Mercury. The first five recognized dwarf planets are Ceres, Pluto, Eris, Makemake and Haumea. Scientists believe there may be dozens or even more than 100 dwarf planets awaiting discovery. The IAU recognized Pluto's special place in our solar system by designating dwarf planets that orbit the sun beyond Neptune as plutoids. Eris, which orbits far beyond Neptune, is a plutoid while Ceres, which orbits in the main asteroid belt between Mars and Jupiter is a dwarf planet. Read More: Mike Brown's Dwarf Planet Page (Caltech)

- Ceres and Pluto are known to be dwarf planets through direct observation. Eris is recognized as a dwarf planet because it is more massive than Pluto (measurements by New Horizons indicate that Pluto's diameter is larger than that of Eris), whereas Haumea and Makemake qualify based on their absolute magnitudes.

- greenish blue Eris is green which is unlike any other planet an very unusual. Eris is also the largest known dwarf planet in the Solar System. It is approximately 2 500 kilom … eters in diameter and 27% more massive than Pluto. Since it is so far away it take Eris about 558 years to orbit around to Sun. Eris was first spotted in 2003 by a Palomar Observatory-based team led by Mike Brown.

Head lice infestation Head lice infestation (also known as pediculosis capitis, nits, or cooties) is the infection of the head hair and scalp by the head louse (Pediculus humanus capitis).Itching from lice bites is common. During a person's first infection, the itch may not develop for up to six weeks.ead lice are generally spread through direct head-to-head contact with an infested person. Transmission by sharing bedding or clothing such as headwear is much less common. The cause of head lice infestations is not related to cleanliness.

- Ceres, minor-planet designation 1 Ceres, is the largest asteroid and the only dwarf planet in the inner Solar System, orbiting in the asteroid belt between the orbits of Mars and Jupiter.It is a rock ice body 950 km (590 mi) in diameter and the smallest identified dwarf planet.t contains about one-third of the mass of the asteroid belt. Discovered on January 1, 1801 by Giuseppe Piazzi, it was the first asteroid to be identified, though it was classified as a planet at the time. It is named after Ceres, the Roman goddess of growing plants, the harvest, and motherly love.

Why is Pluto not a planet? And so, Pluto is a dwarf planet. There are still many objects with similar size and mass to Pluto jostling around in its orbit. And until Pluto crashes into many of them and gains mass, it will remain a dwarf planet. Eris suffers from the same problem.

Eris (dwarf planet) It has one known moon, Dysnomia. As of 2011, its distance from the Sun is 96.6 AU, roughly three times that of Pluto. With the exception of some comets, Eris and Dysnomia are currently the most distant known natural objects in the Solar System. Because Eris appeared to be larger than Pluto, its discoverers and NASA initially described it as the Solar Systems tenth planet.

Former â10th planetâ officially named Eris LOS ANGELES — A distant, icy rock whose discovery shook up the solar system and led to Pluto's planetary demise has been given a name: Eris. The christening of Eris, named after the Greek goddess of chaos and strife, was announced by the International Astronomical Union on Wednesday.

Dwarf Planets of Our Solar System (Infographic) The solar system's erratic ninth planet, Pluto, was assigned to the new “dwarf planet” category along with four other bodies, all tinier than Earth’s moon. Some astronomers expect there may be as many as 50 dwarf planets in the solar system. Eris, the largest dwarf planet, is only slightly bigger than Pluto, at 1,445 miles in diameter (2,326 km). Discovered in 2003, Eris orbits at an average distance of 68 AU (that is, 68 times the Earth’s distance from the sun) and takes 561.4 Earth years to circle the sun. Eris has the orbit that is most highly inclined of all the dwarf planets, tilted nearly 47 degrees from the plane of the planets’ orbits. A day on Eris takes 25.9 hours.

What is the difference between a dwarf planet and a regular planet? (2) A dwarf planet is a celestial body that: (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape2, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.o far, all known dwarf planets are beyond the orbit of Neptune, in the Kuiper belt. I believe there is a size issue, however, I don't know what the limit is. The diameter of Pluto, Eris (formerly called Xena), Sedna and Quaoar are below 3000 km.

- It is also the ninth-most-massive known body directly orbiting the Sun, and the largest known body in the Solar System not visited by a spacecraft. It is measured to be 2,326 ± 12 kilometers (1,445.3 ± 7.5 mi) in diameter. Eris is 27% more massive than dwarf planet Pluto, though Pluto is slightly larger by volume. Eris' mass is about 0.27% of the Earth's mass. Eris was discovered in January 2005 by a Palomar Observatory-based team led by Mike Brown, and its identity was verified later that year.

Pluto Facts Discovered in 1930, Pluto is the second closest dwarf planet to the Sun and was at one point classified as the ninth planet. Pluto is the largest dwarf planet but only the second most massive, with Eris being the most massive.luto’s Moons (Size & Orbits). Pluto is the largest dwarf planet: At one point it was thought this could be Eris. Currently the most accurate measurements give Eris an average diameter of 2,326km with a margin of error of 12km, while Pluto’s diameter is 2,372km with a 2km margin of error.

Dwarf Planets This picture shows the sizes of the original three dwarf planets (Pluto, Ceres, and Eris) as compared to Earth. It also shows Pluto's large moon Charon (and its two small moons Nix and Hydra) and Eris's moon Dysnomia to scale.None of the distances between objects in this image are to scale.here are currently five official dwarf planets. Pluto, formerly the smallest of the nine traditional planets, was demoted to dwarf planet status. Ceres, the largest asteroid in the main asteroid belt between Mars and Jupiter, was also declared a dwarf planet.

Eris (dwarf planet) Eris is 27% more massive than dwarf planet Pluto, though Pluto is slightly larger by volume. Eris's mass is about 0.27% of the Earth 's mass. Eris was discovered in January 2005 by a Palomar Observatory –based team led by Mike Brown, and its identity was verified later that year.his was announced as the IAU's Definition of a Planet in the Solar System, adopted on August 24, 2006. At this time, both Eris and Pluto were classified as dwarf planets, a category distinct from the new definition of planet.

- Both Pluto and Eris show these signatures. At the very low temperatures of Pluto and Eris, methane, which is in gaseous form on the earth, is frozen solid. The interior of Eris, like the interior of Pluto, is likely a mixture of rock and ice. Pluto and the new dwarf planet are not completely identical, however.

Mike Brown talks about dwarf planet bigger than Pluto Mike Brown talks about dwarf planet bigger than Pluto. In 2007, when astronomers measured the mass of the dwarf planet Eris, they found that it’s 27% more massive than Pluto. Astronomer Mike Brown, who discovered Eris, said, “We got lucky in that Eris has a moon going around it.
