WTH is Going On? There Are About 400 Planets in Our Solar System Says Top Space Expert

there is nothing so far removed from us to be beyond our reach or so far hidden that we cannot discover it to this end we will explore and pose questions what is a planet the ancient Greeks looking up at the night sky I realized that some of the points of light moved against the background of stars they called these lights planets meaning wanderer for thousands of years this scientifically inexact word was sufficient to distinguish other objects in the sky from the stars as the power of telescopes increased our ability to see into the depths of space our understanding of the solar system evolved by the middle of the 19th century we listed 15 planets in the solar system Mercury Venus Earth Mars Ceres Pallas Juno Vesta Astraea Hebe iris Jupiter Saturn Uranus and Neptune within 50 years we had concluded that an additional term was needed to properly describe what we had discovered the asteroid belt at the beginning of the 20th century Ceres Pallas Juno Vesta Astraea Hebe and iris were referred to as asteroids and we believe that our solar system included the eight planets clearly visible through our telescopes and at least one more yet to be found Pluto was discovered in 1930 and was hailed as the ninth planet even though at the time some astronomers did not think the term planet accurately described the new fine by 2005 many believed we had identified the tenth planet in our solar system nicknamed Xena later officially designated Eris this distant icy object slightly larger than Pluto read the debate over what exactly is a planet as we continue to explore our solar system and our technology continues to improve we are seeing more and more objects on the distant fringe of our solar system that need to be defined and classified much like other Sciences such as biology where one may discover a new species classification is a common and needed process which groups like objects for purposes of comparison and further study and as in all sciences classification can and should change based on new knowledge the International Astronomical Union a renowned organization dedicated to promoting and safeguarding the science of astronomy recently took up the debate over what is a planet while many accept the definition issued by the IAU scientists worldwide continue to debate the issues and there are many national and international science organizations who have not weighed in in this first attempt of scientifically defining a planet the IAU said that a planet must have these three traits it must be a body that is in orbit around the Sun it must have sufficient mass so that its own gravity pulls it into a nearly round shape and the object must clear away other objects in its neighborhood the resolution further defined a new category called dwarf planet which has these four following traits it too is in orbit around the Sun it also must have sufficient mass so that its own gravity pulls it into a nearly round shape however it has not cleared its neighborhood and it cannot be a moon the second iae resolution made Pluto the prototype of the newly created category called dwarf planet Pluto as well as Eris are not dominant enough for their gravitational fields to have incorporated or shoved aside all of their neighbors in fact based on current knowledge they are only two bodies in a large field of thousands to millions of similar objects known as the Kuiper belt it is not surprising then that we have only catalogued a very small percentage of the Kuiper belt and that only in the past ten years the stilt for exploration is vast in the future pluto eris and untold other objects in the Kuiper belt which have yet to be discovered might be included in a new classification system as dwarf planets although the IAU was the first to try to scientifically define a planet many astronomers disagree with the definition as it classifies a planet in large part by what it is near and not by its properties based on the IAU ruling if the earth were in the Kuiper belt it would not meet the current ia you definition of a planet also Jupiter with its shared orbital asteroids known as the Trojan asteroids hasn't cleared its orbital path so it too might not be considered a planet the topic of defining a planet is still being vigorously debated

  1. Pluto ceres makemake eris and hamuei are not planets they are dwarf planets the planets are MERCURY Venus earth mars Jupiter saturn uranus Neptune was the 8 planets you will be death

  2. Stupid, stupid, Stupid. We have NINE plants: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto (eight planets if you want to count Pluto as a dwarf planet).

    WHAT are these people ON? I mean, take this stuff and you're in interstellar space!! Yep. Take whatever these folks are and you won't need a rocket!

  3. Hello folks, I published 4 videos on youtube where I prove that celectial bodies are hollow. It's the theory of everything. Check it out. https://youtu.be/FRomfZu4KYQ https://www.youtube.com/watch?v=oyue6R7l8PI https://youtu.be/5PrF49vEJT0 https://youtu.be/IRQhshA3kVA

  4. The problem is scientists expect other planets to the same patterns as earth. Scientists need to just accept that the other planets exist with their own pattern of rotation and orbital pull to the sun.

  5. Anything above half a meter long objects should be under the influence of suns and the planet around them exactly how many under sun and the planet not known.

  6. Who cares what you call them? Eris and other "dwarf" planets are still worlds . Pluto even has a sizeable moon,Charon.

  7. WTF Jupiter isn't orbiting the sun look at earth is is orbiting the sun yes it goes around in in circles does Jupiter do the EXACT SAME THING!? YES "top Space expert" you are WRONG!

  8. "Jupiter dors not orbit the sun so Jupiter is not a pkanet accorfing to the new deginition" What about!? explain it pls
