Exploration There have been no missions to date to Eris or any missions planned for the future at this time.
Eris was initially known as the tenth planet. However, no objection was raised to the Sedna name other than the breach of protocol, and no competing names were suggested for Sedna.
The diameter of Eris is about 2, km 1, miles. On September 13, this name was accepted as the official name by the IAU. Sun accounts for Similarities to Eris and Pluto suggest that it may be similar in internal structure as Pluto, but may have a more solid and larger core than Pluto.
According to studies undertaken it is understood that below the frozen exterior of ice, there is a sea of liquid water present. After a lot of discussion, astronomers decided to make up a new category for objects like Eris.
It is approximately 97 AU Astronomical Units away from the Sun, and is three times farther than Pluto, taking twice as much time years to orbit the Sun, as compared to Pluto.
If it really is 2, km across then it is a little larger than Pluto, which has a diameter of 2, km 1, miles. After a lot of discussion, astronomers decided to make up a new category for objects like Eris.
Name[ edit ] Initially, Eris was given a provisional designation, the so called "license plate" name and then eventually a name based on Earth mythology. Because Eris was initially thought to be larger than Plutoit was described as the " tenth planet " by NASA and in media reports of its discovery.
The diagram on the left is a polar view whereas the diagrams on the right are different views from the ecliptic.
Jupiter is a gaseous planet and so it does not have a solid surface, because of it being made out of gas it technically has no surface.
At its Perihelion closest to the sun it is 5. All affairs of human life are divided into 12 classes and each class of affair is in the domain of one or the other house of the chart. It was inspired by the title character of the television series Xena: Solar System About 4, million years ago, the Solar System was just a spinning disc of dust and gas.
It was called "Gabrielle", the name of another character from the TV show. The arcs below the ecliptic are plotted in darker colors, and the red dot is the Sun. It orbits in a nearly circular orbit around Eris and aided in helping astronomers to calculate Eris' size and mass. However, during its aphelion, these gases become heavy again and fall frozen back to the surface of the planet becoming the equivalent of snow and ice on Earth.
The orbit is not a circleso Eris moves closer to and further from the Sun as it goes around. This also indicates there may be snow and dew on the surface as its weather patterns as it goes from perihelion to aphelion in its rotation. Last modified February 10, by Randy Russell.
But because they were smaller they soon cooled down and became planets. Only during its perihelion does it turn gaseous and may create a form of atmosphere.
All affairs of human life are divided into 12 classes and each class of affair is in the domain of one or the other house of the chart. Eris has an unusually eccentric orbit. Current technology and the inability to travel such a major distance to get a better understanding of Eris is not available at this time.
Eris is the brightest planet, 2nd most reflective body, in our solar system. Eris was one of the first three objects classified as a dwarf planet, along with Pluto and Ceres.
The orbit of Eris is also tilted The team had planned to delay announcing their discoveries of the bright objects Eris and Makemake until further observations and calculations were complete, but announced them both on July 29 when the discovery of another large TNO they had been tracking, Haumeawas controversially announced on July 27 by a different team in Spain.
Routine observations were taken by the team on October 21,using the 1. Windows to the Universe Community News. Routine observations were taken by the team on October 21,using the 1. As far as I remember this was the only time I told anybody this in the press, and then it got everywhere, which I only sorta felt bad about—I kinda like the name.
But because they were smaller they soon cooled down and became planets. The orbit of Eris is also tilted Even traveling at the speed of light, it would take 12 hours to reach the planet which is an equivalent of 18 years at our current spacecraft velocity.
If it really is 2, km across then it is a little larger than Pluto, which has a diameter of 2, km 1, miles. Eris: The Dwarf Planet in the Solar System UniverSavvy Staff Sep 30, Eris, the largest of the dwarf planets was officially identified inby Michael Brown and his.
Eris (Xena): Our Solar System Essay Sample. Discovery images of the dwarf planet Eris. The three images were taken 1 1/2 hours apart on the night of October 21st, Eris can be seen very slowly moving across the sky over the course of 3 hours.
Eris was discovered in July, by Mike Brown of CalTech and his team. Eris News. Eris, formerly known as Xena, is the largest dwarf planet in our solar system. Eris has a moon known as Dysnomia.
Eris was first spotted in during a Palomar Observatory survey of the outer solar system by Mike Brown, a professor of planetary astronomy at the California Institute of Technology; Chad Trujillo of the Gemini Observatory; and David Rabinowitz of Yale University.
At the end of the conference, IAU members voted to demote Pluto to dwarf-planet status, leaving the solar system with eight planets. However, the ruling effectively settled the year-long controversy about whether Eris would rise to planetary status.
