BBC NEWS | Science/Nature | Astronomers detect ''10th planet''
Astronomers in the United States have announced the discovery of the "10th planet" to orbit our Sun. The largest object found in our Solar System since Neptune in 1846, it was first seen in 2003 - but important details have only now been confirmed.
Astronomers say a Neptune-sized planet lurks beyond Pluto
The solar system appears to have a new ninth planet. Today, two scientists announced evidence that a body nearly the size of Neptune—but as yet unseen—orbits the sun every 15,000 years. During the solar system''s infancy 4.5 billion years ago, they say, the giant planet was knocked out of the planet-forming region near the sun.
Eris (dwarf planet)
Eris is the ninth-most massive known object orbiting the Sun and the sixteenth-most massive overall in the Solar System (counting moons). It is also the largest known object in the solar system that has not been visited by a spacecraft.

Eris
The new ruling reclassifies Pluto as a dwarf planet and reduces the number of planets in the solar system to eight. Both Eris and the asteroid Ceres are also classified as dwarf planets. Sep 14, 2006: The International Astronomical Union (IAU) announces that the dwarf planet known as Xena will be called Eris, after the Greek goddess of discord.
Jupiter
Jupiter is the fifth planet from the Sun and the largest in the Solar System is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Its diameter is eleven times that of Earth, and a tenth that of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm), with an orbital
Caltech Researchers Find Evidence of a Real Ninth Planet
2 days ago· Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion
ASTR 1033 Ch 12 Flashcards
_____ are large enough to resemble planets in their behaviors, but are too small to dominate their regions of the solar system c) Eris is similar to Pluto, which was once considered the ninth planet. After the discovery of Eris, astronomers created a new category called "dwarf planets" and excluded Pluto from the category of planets.

10 Things You Should Know About Eris, The Solar System''s "10th Planet"
4. Estimates of Eris'' size have changed over time and the development of observational techniques. According to the latest data, the diameter of the planet is over 2360 km. 5. Eris approaches the Sun and moves away from it in the range from 5.7 to 14.5 billion km. Thus, one revolution around the star takes more than 560 Earth years.

Is there a Planet X or 10th planet?
There is no known Planet X or 10th planet in our solar system. Scientists have been looking for about a hundred years. Scientists have been looking for about a hundred years. It was believed that such a planet was required to explain the orbital characteristics of
Hypothetical Planet X
This hypothetical Neptune-sized planet orbits our Sun in a highly elongated orbit far beyond Pluto. The object, which the researchers have nicknamed "Planet Nine," could have a mass about 10 times that of Earth and orbit about 20
Tenth Planet: The Next World in the Solar System
Before 1930, there were 8 planets in the Solar System. And then with the discovery of Pluto in 1930, the total number of planets rose to 9. There really is no 10th planet, in fact, we don''t
In Depth | Hypothetical Planet X
The announcement does not mean there is a new planet in our solar system. The existence of this distant world is only theoretical at this point and no direct observation of the object nicknamed "Planet 9" have been made. The mathematical prediction of a planet could explain the unique orbits of some smaller objects in the Kuiper Belt, a distant

A star that hosts planets orbiting around it is called a planetary system, or a stellar system, if more than two stars are present. Our planetary system is called the Solar System, referencing the name of our Sun, and it
6 FAQs about [Is there a tenth planet in the solar system]
When was the 10th planet discovered?
The discovery was confirmed in January 2005 after the team examined the pictures obtained from the survey in detail. At the time of it’s discovery, Brown and his colleagues believed that they had located the 10th planet of our solar system, since it was the first object in the Kuiper Belt found to be bigger than Pluto.
Could a tenth planet cause strange orbits in our Solar System?
Either way, our little solar family is going to continue to grow with these long-lost distant relations. Scientists think that the gravitational influence of a tenth planet that is roughly the size of Mars could be the cause of strange orbits in our solar system.
Why is Eris a tenth planet?
Because Eris appeared to be larger than Pluto, NASAinitially described it as the Solar System's tenth planet. This, along with the prospect of other objects of similar size being discovered in the future, motivated the International Astronomical Union(IAU) to define the term planetfor the first time.
Is there a new planet in our Solar System?
The object, which the researchers have nicknamed "Planet Nine," could have a mass about 10 times that of Earth and orbit about 20 times farther from the Sun on average than Neptune. It may take between 10,000 and 20,000 Earth years to make one full orbit around the Sun. The announcement does not mean there is a new planet in our solar system.
Is there a true Planet Nine?
Case in point, last year, scientists at the California Institute of Technology proposed that there might be a true Planet Nine in our solar system. The team asserted that it appears to be 10 times the mass of Earth and that it is hiding out in the remote recesses of our solar system—well beyond the orbit of Pluto.
