New planets?

Question

I read on the news we have 3 new planets.... Xena is one of them? Is this true? Wow... 12 planets. Sweetness!

Answer 1

The International Astronomical Union (IAU) may adopt Xena as the name for UB 313. Michael Brown of the California Institute of Technology who discovered the planet nicknamed it Xena after the warrior princess of TV fame. He chose Xena because it would be the 10th planet which is "X" in roman numerals. Gabrielle is the proposed name for the moon of Xena.

The 12 planets in our solar system listed in order of their proximity to the sun would be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon, and Xena (UB313). Pluto's largest moon, Charon; and the asteroid Ceres would be categorized as planets. Pluto would be categorized as both a planet and a pluton. Both Pluto and Charon each are large enough (massive enough) to be spherical. Both bodies independently satisfy the definition of “planet”. The reason they are called a “double planet” is that their common centre of gravity is a point that is located in free space outside the surface of Pluto.

The center of gravity for the Moon's orbit is in the center of the Earth. The Moon truly orbits the Earth.

The new definition of a planet: any round object larger than 800 kilometers (nearly 500 miles) in diameter that orbits the sun and has a mass roughly one-12,000th that of Earth. Moons and asteroids will make the grade if they meet those basic tests.

The growing category of "plutons" - Pluto-like objects that reside in the Kuiper Belt, a mysterious, disc-shaped zone beyond Neptune containing thousands of comets and planetary objects.
Plutons are distinguished from classical planets in that they reside in orbits around the Sun that take longer than 200 years to complete (i.e. they orbit beyond Neptune). Plutons typically have orbits that are highly tilted with respect to the classical planets (technically referred to as a large orbital inclination). Plutons also typically have orbits that are far from being perfectly circular (technically referred to as having a large orbital eccentricity). All of these distinguishing characteristics for plutons are scientifically interesting in that they suggest a different origin from the classical planets

Answer 2

There is still some debate over allowing these. The problem is that Xena, and probably the other two, are as large or larger than Pluto, so excluding them from the list of planets seems foolish. What some have proposed is a new way to classify the planets, instead of clumping gas giants like Jupiter with tiny pieces of ice like Pluto, grouping them by their type. It will make it a bit more difficult to teach (no more mnumonic), but it will make more sense.

Answer 3

i'm no longer announcing that i've got faith in Planet X or Nibiru yet one question to contemplate is how did a civilization 4000 plus years in the past became waiting to chart our photograph voltaic equipment? in the event that they weren't visited via E.T.s then they ought to have had progressed technologies to make certain out of our planets ecosystem and extremely deep in to our photograph voltaic equipment. if it rather is the case then why did it take each of how in to the mid 1900's to re-detect the those planets? Did the human race exchange into much less intellegent throught the years? Mentally de-evolve? And interior the sumer "translated" and pictured tableture it shows how while bodily watching a chart of our planets the dimensions transformations on a small scale assessment to a minimum of one yet another and its extremely precise... and it shows a planet X..... so its perplexing to rule the planet x thought out. even though it doesnt say something approximately specific doomsday. that's perplexing to rule out a planet x in specific because of fact that this previous month 32 planets have been dicovered.... exoplanets and "large earths" so if those exsist then why can not planet x or nibiru? no longer announcing they are the comparable... purely individuals that are too scared to confess the possibltiy of a planet X or E.T. exisitance because of feeling no longer almost as good as a extra progressed race would desire to void any of those questions out. And if a civilization 4000 years in the past would desire to be extra progressed than what we've been interior the early 1900's in area exploration then why couldnt there be a planet x and approximately it rather is orbit? nicely i'm beneficial that someplace accessible there could be an intellegence able to controlling an ecosystem... or hell it would desire to easily be a dying celebrity off celebrity wars ( frightening.... hqhahahah) the two way no longer something is impossible... no matter the way you seem at existence and its advent, all of it seems impossible yet its no longer for we are alright here marvelous?

Answer 4

The three planets are Ceres, Charon, and Xena (pronounced kA-race, kaah-ron, and xA-naah respectively in their ancient languages).

Answer 5

I heard about it too! What wonderful uses for technology! Finding new planets! Way cool!!
