Planets : Quick 10 Questions to Test Your Knowledge

Planets  are a celestial bodies orbiting a star . In 2006, the International Astronomical Union officially adopted a resolution defining planets within the Solar System. This definition has been both praised and criticized, and remains disputed by some scientists.Some of the planets are part of the Solar System which consists of the Sun and the astronomical objects gravitationally bound in orbit around it. The four smaller inner planets, Mercury, Venus, Earth and Mars, also called the terrestrial planets. The two largest, Jupiter andSaturn, are composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune.

  1. I am helping my daughter with a science project and would like to know specifically why planets that are closest to the sun orbit faster than further planets? I am having difficulty finding a specific explaination. Serious answers only. Thank you!

  2. Religion pre-decides what nature is without much evidence or understanding of what nature is. Whereas science lets the experiments and the equations decide what nature is.

    She’s gonna come out as she is, and science is there to observe her as she is.

    But not religion. It pre-decides what she is. And it’s been demonstrated before that religion has been wrong; and it’ll be wrong again.

    And science is a continuous process. Science is always trying to understand her as she is. But not religion. Religion is stuck on seeing things in only religion’s way. And religion never likes to be corrected.

    Science and religion are incompatable.

  3. Why are the inner planets small and the outer planets huge!

  4. wHAT HAPPENS TO THE ELEMENTS IN IRON ORE WHEN THE ORE IS MIXED WITH CARBON AND HEATED

  5. Apparently, there are material planets in hinduism where different demigods/deities/devas reside like the planet Bramhaloka. What exactly are they. Are they just different planets with higher beings of life form? Can any of these planets be proven scientifically, because according to hinduism they exist in this material universe.

  6. It’s purely antecdotal but it feels like the amount of science literacy has gotten worse in recent years. What can we do to reverse that trend? Should we throw money at it? Give incentives to schools that do well in science? Make the standardized tests harder? More scholarships for science majors? Start a new PR campaign that makes science cool? Have the government appoint someone as a Science Ambassador? What do you think would work best?

  7. In 1967, the Sun, the Moon, and five planets visible with the naked eye were all in conjunction with each other during a solar eclipse. This made the viewing of Mercury, Mars, Saturn, and what two other planets possible?

  8. Do all the planets orbit the sun in a single plane, or do they have their own planes of orbit (forming an ellipsoid)?

    I suspect that they are not all in a single plane. This is because, when we see the planets in the sky, we need to look above into the sky, each planet seen at various angles from the Earth’s horizon. Further, if all the planets were in the same plane we should not have been able to see them.

    If they are not in a single plane, is it only for ease of representing that all pictures of the solar system depict the planets in a single plane with the sun?

  9. Hi,

    Mathematics and computer science are not natural sciences, applied sciences (technology) or social sciences.
    So, what kind of sciences are they?

    I found out that they may belong to constructive sciences or formal science but I am not sure.

    PLEASE DO NOT ANSWER WITH LINKS.

    Thanks.

  10. I just got a novice level telescope for Chirstmas and I want to know where to look in the sky for planets. I live in the outskirts of Pittsburgh. Are there any websites listing where planets are right now or maps?

  11. Can any1 tell me the size(in relation to earth) of all the planets of the solar system?
    Or gravity (in relation to earth) of all planets of the solar system

  12. What is more important to the self; science or a temprament and attitude of science in self.

    Is there any science which can help the self to enable and empower itself with knowledge and wisdom of self to enable and empower the self with an attitude and a temprament of science.

    What is this science; where can it be known and studied; how can it be practised. Can this science also help the self to enable and empower itself with knowledge and wisdom of any type and kind.
    Can we also use this science to help ourselves for enabling and empowering ourselves with that knowledge and wisdom which had been the cause, purpose, and reason of the existance, presence and working of self and the religion and god of self.

  13. I need to know some ways to change the viscosity of a liquid. I already have temperature, which is an obvious one. There are no sites that help me and I need more then one way. Please help!
    (grade 8 science)

  14. I’m writing an essay on how literature and science affect the understanding of humanity and society. I’ve got the literature part down pretty well, but I am absolutely stuck on the science part. I have to choose either between natural sciences or human sciences and relate it to reason, but I don’t have any specific examples. Can you give me a few?

  15. give me three kinds of bacteria that causes diseases

    and name me one kind of protist that causes disease and leave links that would be helpfull if you want 10pts

  16. When the earth is overpopulated there will be migrations of people to live on other planets which will be terraformed for future homes.How many planets are habitable for the human race?

  17. Our solar system has 8 planets, and some have 1 or 2 planets. I want to know what the average number of planets in a solar system is.

  18. A. As Earth passes another planet, its gravitational pull slows down the other planet so that it appears to be traveling backward.

    B.When planets are farther from the Sun, they move slower than when they are nearer the Sun; it is during this slower period that they appear to move backwards.

    C.The other planets never really appear to move backward; the background stars shift due to Earth’s revolution around the Sun.

    D.As Earth passes another planet, the other planet appears to move backward with respect to the background stars, but the planet’s motion does not really change.

    E.Apparent retrograde motion is an illusion created by turbulence in Earth’s atmosphere.

  19. which planet is the biggest?
    which planet has the longest year?
    which planet is the hottest?
    which planet is the coldest?
    which planet has the shortest year?
    which planet is the smallest?
    how may planets that are descoverd that have water and air?
    and how may universas are there??

  20. Earth has been the only planet since millions of years with the proof of life.All other planets are merely assumptions by astrologers that earth-like planets exist beyond our Milky way. Recently an earth like planet was discovered by astrologers which was supposed to have life, fire,water and Oxygen like gas.But that is all a foolish assumption.

  21. I’m looking at a college and it says you have to have 3 years of lab science. What classes are those? I took earth science last year, and am planning on taking Chemistry, Chemistry II (not sure of the exact name) and physics. Are all of those lab sciences or what?

  22. give me prof that scientific laws can change!

  23. When I search it all of them have different planets and they seem a bit dated. Can anyone tell me where all the dwarf planets are, i know theres one between mercury and jupiter, and there’s pluto are there anymore?

  24. I have limited science knowledge, currently studying economic in University. I would like to become a dermatologist to help others with their skin problems. Is it too late to start studying science, then apply for med school?

  25. Which planets are active? Are Earth, Venus and Mercury all active? And if so, what makes them geologically active?

  26. Lots of science shows, catchy music to go along with learning about the planets, witty science writers, etc. Does this all really help in knowing the type of work/preparation that is required for science disciplines? I’m thinking of people planning to begin a course of study in science. I suppose a measure of popularity is okay for the general public.

  27. All planets are observed to revolve in the same direction around the Sun. Additionally, most planets rotate in this same direction around their axis. How does the solar nebula theory explain this?

    Science provoked different laws, theories and observations about each and every phenomena and still continue to explain such phenomena that is beyond our knowledge…. Does Science really provide a sufficient and adequate information in explaining such phenomena?. If yes, justify your answer, If not, can you please discuss an example of a phenomena that science can’t really explain.

  29. Science describes the universe, ideology comments on it.

    Then again, ideologues have created their own universe.
