It is the most distant discovered dwarf planet from the Sun and has the greatest mass of the five dwarf planets. It was nicknamed Xena by the team, and later named Eris, after the ancient Greek goddess of discord and strife. The name fits since Eris remains at the center of a scientific debate about the definition of a planet.
It is the second largest dwarf planet, almost as big as Pluto. When Pluto was still considered a planet, and Eris was discovered, it was considered to be the 10 th planet of the Solar System. It has an average distance of 68 AU away from the Sun.
Its actual distance can be checked online, as Eris is constantly tracked. Its apparent magnitude of Formation Eris is a member of a group of objects that orbit in a disc-like zone beyond the orbit of Neptune, called the Kuiper Belt. Structure, Surface and Atmosphere Eris has an estimated albedo of 0. Moons Eris has one known satellite, a moon that was discovered in , and was named Dysnomia, after the daughter of the goddess Eris.
Dysnomia Dysnomia is the second known largest moon of a dwarf planet. Life Habitability Due to extreme cold temperatures, it seems unlikely that life could exist there. Did you know? Eris is currently in the Cetus constellation and it will enter the Pisces constellation in At its furthest point from the Sun is reaches outside the Kuiper Belt, yet at its closest point it is much closer to the Sun than Pluto, when Pluto is at its furthest.
It is currently at its furthest point away from the Sun. Because of its distance any atmosphere it might have had, would have frozen and fell to the surface as snow.
But as it will get closer to the Sun in about years, its icy surface will sublimate, creating a new tenuous atmosphere. 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. Standing on Eris would make a person feel lighter, as its gravity is 11 times weaker than that of Earth, making a person eleven times weigh less. Though its gravity is weak compared to earth, Eris has the strongest gravity out of all the dwarf planets: 0. If a person would stare into the sky from Eris, he or she would see a very sharp view of the Milky Way, and the stars, since atmosphere could not get in the way.
The most spectacular view would be that of its moon, Dysnomia, which is around kilometers or miles in diameter while also a big advantage would be the fact that it is pretty close to Eris, orbiting its parent planet at only In the organization responsible for classifying celestial bodies, the International Astronomical Union, decided that a new class of objects was needed. 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, miles in diameter 2, km. A day on Eris takes Eris has one moon, Dysnomia. Pluto , discovered in , orbits the sun at an average of Its diameter is 1, miles 2, km. Pluto takes Potential for Life Potential for Life The surface of Eris is extremely cold, so it seems unlikely that life could exist there.
A 3D model of Eris, a dwarf planet in the Kuiper Belt. The next full Moon is the Beaver Moon, and there will be a near-total lunar eclipse. Full Moon Guide: November - December DART team members have filled the spacecraft with fuel, and are running rehearsals as they approach launch on Nov. The solar system is encased in a bubble called the heliosphere, which separates us from the vast galaxy beyond.
Studying the Edge of the Sun's Magnetic Bubble. Over the next 12 years, Lucy will fly by one main-belt asteroid and seven Trojan asteroids. JPL's lucky peanuts are an unofficial tradition at big mission events. Full Moon Guide: October - November A new paper details how the hydrological cycle of the now-dry lake at Jezero Crater is more complicated than originally thought.
DART's mission is to determine if flying a spacecraft into a small solar system body could be a reliable technique to deflect an asteroid. The spacecraft will continue collecting data about Mars, but engineers will stop sending commands until mid-October. Winds in the outermost "lane" of Jupiter's Great Red Spot are accelerating — a discovery made possible by Hubble. The dusty rocks of Jezero Crater are beginning to tell their story — thanks to the seven powerful science cameras aboard Perseverance.
NASA's Lucy is set to launch in October on the first mission to study the Trojan asteroids — swarms of asteroids associated with Jupiter. Lucy Is Going to Space! Researchers will use Webb to observe 17 actively forming planetary systems. The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study three big quakes. This year, the minimum extent of Arctic sea ice dropped to 1. Futuristic electric thrusters emitting a cool blue glow will guide the Psyche spacecraft through deep space to a metal-rich asteroid.
