Would u like seein this in future-Number planets in solar system=infinite- NO? then go in and write yr opinion
Question:
and so pluto is no more a planet and if u wanna call it a planet then dozens of other bodies revolving around the sun should be called "planets" how ridicolous it is, will we end having 46,592 planets after few years on more objects discovery or what!! think about it people PLUTO CAN NEVER BE ANYMORE A PLANET!
plz write your opinion
Answer:
The reason for the changes is to make the classifications uniform and based on characteristics of how the asteroid/planet was formed, the orbit, the shape and other factors.
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 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.
By loose interpertation of size almost all the moons can be considered planets, however these objects revolve around a larger body and not our central sun. As far as the debate think what the people in the past had to deal with them the outer planets had to be added. I personally think that given there size and their path around that sun that we should go beyond 9.
WOW! Did you say that all in one breath or did you have to pause for a breath? Grammer, dude...
As for what makes a planet, I personally don't care anymore. If the scientists all decide that the small particle of dust floating in orbit around the gas giant Jupiter is to be called a planet, then so be it!
