- An Eridian day is just slightly longer than Earth’s.
- Eris was once thought to be bigger than Pluto.
- Eris is responsible for the big debate over the definition of “planet.”

What is Eris moon called?
Dysnomia
Eris/Moons
Eris has a very small moon called Dysnomia. Dysnomia has a nearly circular orbit lasting about 16 days. This moon is named after Eris’ daughter, the demon goddess of lawlessness. Dysnomia and other small moons around planets and dwarf planets allow astronomers to calculate the mass of the parent body.
What is special about Eris?
Though Eris is only the second-largest dwarf planet, it is the most massive of the five. Additionally, it is the farthest from the Sun of them all. Since Eris is located beyond Neptune, it is considered a trans-Neptunian object (TNO). The location of Eris is unique among other dwarf planets.
What is Eris composition?
The surface of Eris can be modeled using two areas of distinct composition: about 50% appears to be covered with pure methane ice, while the rest of its surface would be made of an intimate mixture of methane, nitrogen and water ices, and ice tholin.
How long is one day on Eris?
25.9 hours
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 Eris made of?
Results. The surface of Eris can be modeled using two areas of distinct composition: about 50% appears to be covered with pure methane ice, while the rest of its surface would be made of an intimate mixture of methane, nitrogen and water ices, and ice tholin.
How was Eris formed?
It is believed that Eris was originally located inside the Kuiper Belt, but due to gravitational interactions with Neptune, as the Solar System was forming, the dwarf planet was forced out into the scattered disc region. Eris has a surface size similar to that of Russia.
Who discovered Eris?

Eris/Discoverers
Planet X: 2003 UB313, Eris was discovered by Dr. Mike Brown on October 21, 2003. After multiple observations in July 2005, the discovery of Eris was confirmed and formally announced. Eris is about 14.5 billion kilometers from the sun and is in a very highly tilted orbit compared to the other planets.
How was Eris created?
Researchers think Eris’ surface is probably composed of a nitrogen-rich ice mixed with frozen methane in a layer less than 1 millimeter thick. This ice layer could be the result of the dwarf planet’s atmosphere condensing as frost on the surface as it moves away from the sun, they said.
How long is a year in Eris?

What are some interesting facts about Eris for kids?
Facts about Eris for Kids: Eris is considered to be one of the most massive dwarf planets in our solar system. The orbit of Eris gives it the distinction of not always being the most distant planet.
How many days does Eris have in its orbit?
As Eris orbits the Sun, it completes one rotation every 25.9 hours, making its day length similar to ours. Eris has a very small moon called Dysnomia. Dysnomia has a nearly circular orbit lasting about 16 days. This moon is named after Eris’ daughter, the demon goddess of lawlessness.
Why was the moon Dysnomia named after Eris?
Dysnomia has a nearly circular orbit lasting about 16 days. This moon is named after Eris’ daughter, the demon goddess of lawlessness. Dysnomia and other small moons around planets and dwarf planets allow astronomers to calculate the mass of the parent body.
What’s the temperature on the surface of Eris?
Other estimations about the surface include the temperature. The side of Eris that faces the sun probably doesn’t get any higher than -396 degrees F/-238 C, and the side that faces away from the sun is even colder. There don’t seem to be any of the “secondary dark terrains” that have been found on other moons and dwarf planets.
