Test Your Knowledge on Planets- Fourth 10 Questions Set

Planets

Geography studies starts with the study of universe and planets .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. What are the general features of the solar system, and the solar nebula theory, and give evidence of planetary formation in other places in the universe

  2. When we say milky way, is it what our solar system is called, what exactly is a galaxy and where is our place in it?
    How many solar systems are there?

    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.

  4. I know the scientific understandings of how the solar system was started, by why, and who/what created the solar system? Explain yourself. If you think it was god, who is god? Explain yourself.

  5. 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?

  6. A) The solar system has no irregularities; it is perfectly regular and orderly.
    B) They are too minor to play a role; astronomers ignore them.
    C) Theories of the solar system are entirely based on the many irregularities found among the planets and moons.
    D) The solar system is chaotic, with irregularities the rule.
    E) They introduce a need for flexibility in theories of the solar system’s origin.

  7. 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.

  8. 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!

    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.

  10. What made the planets move through space and what caused them to form gravity and a magnetic field and all that complex stuff. And how come earth is the only planets with life in the solar system?
    I am a christian so no big bang stuff.

  11. How much solar system setup for running power a home might costs ? I am from India and their are too many power cuts , so i have decided to setup solar system instead of buy a generetor or invertor , and can any one tell me which company in India supply Solar system setup for home

  12. We just signed with the pool company today and they will begin the work to install an inground pool in our yard. I’ve asked that they put in the necessary plumbing so that we can add the solar system later (paying approx $400 for 3 pipes?). How difficult is it to do this? Is this something relatively simple/straightforward? I should add that we have a computer control panel, so according to our pool man, we should be able to hook up to it and have it controlled remotely. So my question is, once it’s stubbed for solar, what are the next steps and best cost approach? Any guidance is greatly appreciated!

  13. 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.

  14. How much space is between planetary systems? I think the next closest one is Alpha Centauri. How far is that once you leave the solar system? I know that voyager spacecraft left our solar system and is somewhere in deep space; can it ever get to another solar system? or are they all just too far away?

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

  16. 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

    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?

  18. 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?

  19. What I mean is – how easy are the planets of our own solar system to spot using radial velocity techniques from some other solar system in the Milky Way?

    4 gas giants would count in our favour, yes? Or are we too indistinct to be spotted?

  20. 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?

    My study guide for this exam for college says….

    During the star formation process, a disk of material forms around the proto-sun. This disk is where planets will form. What properties of the solar system are indicative of the planets forming from a rotating disk?

    I need to know if the answer would be….Heating, Spinning, Flattening…Does anybody know if that would be right?

  22. They only have a simple telescope but how did they know which planets are close. If the size of the planets are the only way to resolve this question but then again. a close planet might be a distant big planet.
    HELP?

  23. Geologists generally agree that the Earth has been hit many times by other objects in the solar system, and most predict that another object will again strike the Earth in the near future. Does our knowledge of the solar system give us a better chance of surviving such a catastrophe? How? What other benefit is it to know the solar system better? How can the position of sun, moon, and planets help us to know our position on Earth? How does knowing the conditions on other planets help us to appreciate Earth? Could there be life on other bodies in our solar system? Why or why not?

  24. I have heard that there are 9 planets but in some movies they say 8 planets.I am confused.

  25. So I installed a solar system I bought at harbor freight and was planning on getting the rest of the panels later. It says to leave the regulator on only when your at home. I was thinking what is the difference between my system and the $10,000 system that a solar company would install in houses.

  26. […] The Universe is all time and also space and also its contents.It includes worlds, moons, small worlds, celebrities, galaxies, the materials of intergalactic space, and all issue and also energy. The size of the whole Universe is unidentified, however there are lots of theories about the composition and also development of the Universe.Click here for Test Your Knowledge on Planets […]
