National Geographic says there may be another planet in our solar system beyond Pluto.

Very interesting.

There's an asteroid in the Kuiper belt with the name Erys. It has quiet a size as I guess equal in it to Pluto, which as the nineth planet of our solar system gotten into a discusion that it's neither it anymore. I say & hope people agree that Pluto is the 9th with it's moons. Did anyone notice there could be a 10th called X... (I forgot the precise number)?

Yes, it makes you wonder how far out our system extends.  I think the Oort Cloud protects us, something like a warp bubble, from external cosmic hazards.

What I heard was that Eris (named for the goddess of strife) was a good 30% or so bigger than Pluto -- and much further away. But there are also quite a few other planetoids out there. Don't quote me on that yet I haven't looked it up on wikipedia or anything like that.

The Kuiper belt (play /ˈkpər/), sometimes called the Edgeworth–Kuiper belt, is a region of the Solar System beyond the planets extending from the orbit of Neptune (at 30 AU) to approximately 50 AU from the Sun.[1] It is similar to the asteroid belt, although it is far larger—20 times as wide and 20 to 200 times as massive.[2][3] Like the asteroid belt, it consists mainly of small bodies, or remnants from the Solar System's formation. While the asteroid belt is composed primarily of rock, ices, and metal, the Kuiper objects are composed largely of frozen volatiles (termed "ices"), such as methane, ammonia and water. The classical (low-eccentricity) belt is home to at least three dwarf planets: Pluto, Haumea, and Makemake. Some of the Solar System's moons, such as Neptune's Triton and Saturn's Phoebe, are also believed to have originated in the region.[4][5]


Since the belt was discovered in 1992,[6] the number of known Kuiper belt objects (KBOs) has increased to over a thousand, and more than 70,000 KBOs over 100 km (62 mi) in diameter are believed to exist.[7] The Kuiper belt was initially believed to be the main repository for periodic comets, those with orbits lasting less than 200 years. However, studies since the mid-1990s have shown that the classical belt is dynamically stable, and that comets' true place of origin is the scattered disc, a dynamically active region created by the outward motion of Neptune 4.5 billion years ago;[8] scattered disc objects such as Eris have extremely eccentric orbits that take them as far as 100 AU from the Sun.[nb 1]


Pluto is the largest known member of the Kuiper belt, if the scattered disc is excluded. Originally considered a planet, Pluto's position as part of the Kuiper belt has caused it to be reclassified as a "dwarf planet". It is compositionally similar to many other objects of the Kuiper belt, and its orbital period is identical to that of the KBOs known as "plutinos". In Pluto's honour, the four currently accepted dwarf planets beyond Neptune's orbit are called "plutoids".


The Kuiper belt should not be confused with the hypothesized Oort cloud, which is a thousand times more distant. The objects within the Kuiper belt, together with the members of the scattered disc and any potential Hills cloud or Oort cloud objects, are collectively referred to as trans-Neptunian objects (TNOs).[

Could be many more of anything out there, even dimensional. Should that surprise us?


It's strange, being a catalyst for things that move outside.
