B) the interstellar medium. d. C) Ida. Its like a teacher waved a magic wand and did the work for me. The Origin of the Solar System l The Big Bang - The Nine Planets What are Nebulae? As a variant they may collide with the central star or a giant planet. In this book, almost all major problems of the planetary formation process were formulated and many were solved. b. Jupiter [73] The orbits of many of these planets and systems of planets differ significantly from the planets in the Solar System. So, what this theory is saying is as follows: Originally, there was a rotating cloud of gas that condensed and flattened out like a pancake. [69] Another possible solution is the growth of the cores of the giant planets via pebble accretion. Streaks of light made when small debris hits our atmosphere are called ________. How do these meteorites support the nebular theory's scenario for the formation of the terrestrial planets? E) have perihelions within the orbits of Mercury. As the sun collapsed to form, gas and dust particles in the nebula collided and slowly migrated toward the plane of rotation of the nebula. Proto-Sol is formed. The resonant orbits of some of the exoplanet systems indicates that some migration occurred in these systems, while the spacing of the orbits in many of the other systems not in resonance indicates that an instability likely occurred in those systems after the dissipation of the gas disk. e. where the ecliptic is. E) terrestrials very close to their star, and transiting its disk. Name the four principal types of solar-system debris; pair them up in terms of composition, Asteroids: Large chunks of metals and rock primarily formed between the orbits of Mars and Jupiter in the asteroid belt, Metereoroids: A meteoroid is a small rocky or metallic body in outer space. C) Earth orbital X-ray images. Solar Nebular Hypothesis: Definition & Explanation - Study.com We say that the shape of a liquid is the same as the shape of its container. Cometary dust tails lag behind the bluish ion tails as the comet rounds the Sun. Many meteorites appear to have formed very early in the solar system's history. C) the Sun is unique, made of nothing but hydrogen and helium. Chapter 4: The Solar System: Interplanetary M, Astrononmy: The Terrestrial Planets: Ch 6, American Literature: Frederick Douglass, Olau, Jeffrey O. Bennett, Mark Voit, Megan O. Donahue, Nicholas O. Schneider. c. with the others, between Mars and Jupiter; their red colour gives them their name C. The jovian planets began from . The extrasolar planets are found mainly by observing the ________ shifts of their stars. a ________. D) comet nuclei E) the asteroid Gaspra. Clumps of interstellar matter left behind in the midplane of the solar disk as it contracted toward its centre gradually coalesced, through a process of Read More solar system C) the jovians. B) only Jupiter Both terrestrial and Jovian planets make up our solar system. So far, beyond the solar system the extrasolar planets found have been mostly The sun and planets formed from a single cloud that was slowly rotating. [74] The in situ growth of hot Jupiters from closely orbiting super Earths has also been proposed. a. true Intro to Astronomy Ch. 8 Flashcards | Quizlet E) Both A and C are correct. According to the solar nebula theory, why are Jupiter and Saturn much more massive than Uranus and Neptune? C) The asteroids all have about the same density. ", "Formation of gas giant planets: core accretion models with fragmentation and planetary envelope", "Clustered Star Formation and the Origin of Stellar Masses", "The onset of collapse in turbulently supported molecular clouds", "The formation of protostellar disks. Ices condensed only in the outer solar system, where some icy planetesimals grew large enough to attract gas from the nebula, while only metal and rock condensed in the inner solar system, making terrestrial . C) mass times weight. III. Earth's interaction with a comet's dust tail Researchers estimate that there is more total mass in the Kuiper Belt than in the asteroid bel, Some meteorites are believed to have come from Mars and the Moon, As a rotating gas cloud contracts, it spins faster. D) rings around the jovian planets. A) Galileo. The only planet with no atmosphere of consequence is ________. Because extrasolar planets are too close to their much brighter parent stars, observers cannot typically observe an extrasolar planet directly. See Answer. [76] The in situ formation of closely orbiting super-Earths would require a massive disk, the migration of planetary embryos followed by collisions and mergers, or the radial drift of small solids from farther out in the disk. A number of possible mechanisms for this migration have been proposed. The Manicouagan reservoir near Quebec is an example of When it comes to the formation of our Solar System, the most widely accepted view is known as the Nebular Hypothesis.

According to the Solar Nebula theory, planets: a. should be a common result of star fomration, b. spins faster due to conservation of angular momentum. The water was brought to the forming Earth by planetesimals that accreted beyond the orbit of Mars. The Laplacian nebular model was widely accepted during the 19th century, but it had some rather pronounced difficulties. According to modern science, what was the approximate chemical composition of the solar nebula?
