What type of object is Eris?
Eris first appeared to be larger than Pluto. This triggered a debate in the scientific community that led to the International Astronomical Union’s decision in 2006 to clarify the definition of a planet. Pluto, Eris and other similar objects are now classified as dwarf planets.
Is Eris a gas or rock planet?
Scientists believe that the surface of Eris is rocky, similar to the surface found on Pluto. It is believed that Eris was originally located inside the Kuiper belt, but that gravitational interactions with Neptune as the solar system formed forced the dwarf planet out into the scattered disc region.
How much more mass does Eris have than Pluto?
New data shows that the dwarf planet Eris is 27 percent more massive than Pluto, thereby strengthening the decree last year that there are eight planets in the solar system and a growing list of dwarf planets.
Does Eris have a core?
Internal heating via radioactive decay suggests that Eris could have an internal ocean of liquid water at the mantle-core boundary. The presence of methane ice indicates that its surface is very similar to that of Pluto and of Neptune’s largest moon Triton.
Who found the 10th planet?

Is there proof of a 10th planet?
Astronomers have found a new planet in the outer reaches of the solar system. July 29, 2005: “It’s definitely bigger than Pluto.” So says Dr. Mike Brown of the California Institute of Technology who announced today the discovery of a new planet in the outer solar system.
Can the Sun explode at any moment?
The Sun won’t explode. Eventually (in five or seven billion years time), the Sun’s life will come to an end. Our star will swell up, becoming something called a “Red Giant” star. It might even get so big that it swallows the Earth whole.
Can humans destroy sun?
In fact, since you’ve got the power to magically replace stellar cores, you would only need to replace the Sun’s core with carbon or oxygen to kill it. It actually doesn’t have enough mass to fuse even carbon. As soon as you replaced the Sun’s core, it would shut off fusion.
Would a supernova kill us?
Risk by supernova type Although they would be spectacular to look at, were these “predictable” supernovae to occur, they are thought to have little potential to affect Earth. It is estimated that a Type II supernova closer than eight parsecs (26 light-years) would destroy more than half of the Earth’s ozone layer.
