What is the frost line in the solar nebula? Explain how temperature differences led to the formation of two distinct types of planets.
Compare and contrast the terrestrial planets to the gas giant planets. Be sure to include differences in size, density, and any special information about any of the planets.
We think the terrestrial planets formed around solid “seeds” that later grew over time through the accretion of rocks and metals.
a) Suppose the Earth grew to its present size in 1 million years through the accretion of particles averaging 100 grams each. On average, how many particles did the Earth capture per second, given that the mass of the Earth is = 5.972 × 10 ^24 kg ?
b) If you stood on Earth during its formation and watched a region covering 100 m^2, how many impacts would you expect to see in one hour. Use the impact rate you calculated in part a. You’ll need the following as well: the radius of the Earth is = 6.371 × 10 ^6 m and the surface area of the Earth is 4??^2Earth

Learn more about this search by visiting NASA's Kepler mission and writing a half-page overview of the project.arrow_forwardExplain our ideas about why the terrestrial planets are rocky and have less gas than the giant planets.arrow_forward
- Question #4: According to the nebular theory, which planet is most likely to be gaseous rather than rocky? A. Venus, because it is the warmest planet and so is more likely to be gaseous B. Mercury, because planets closer to the solar nebula are more likely to be made of gas, like the nebula C. Earth, because the atmosphere consists of nitrogen, oxygen, and other gases, so it is a gaseous planet D. Neptune, because as the planets get farther from the solar nebula, their composition is more icy and gaseous e Education TM Inc. RK12arrow_forwardDo you think Earth could retain an atmosphere of nitrogen for the age of the Solar System? Explain why or why notarrow_forwardA new Terrestrial planet has been discovered orbiting a nearby Sun-like star. Astronomers have obtained spectra of this planet and determined that the atmosphere is composed of roughly 99% CO2, and the remaining 1% is mostly N2 and is very thin compared to Earth's atmosphere. Briefly describe how the planet could have developed such an atmosphere.arrow_forward
- Which of the following observations would support the solar nebula theory over the passing star hypothesis? a. Proving that most of the sun-like stars near the sun also have planets orbiting them. b. Proving that none of the stars near the sun has planets orbiting them. c. Finding a planet located beyond the orbit of Pluto. d. Finding a meteorite whose age proved to be greater than 4.6 billion years. e. Proving that Mercury has the same uncompressed density as Earth.arrow_forwardHow do terrestrial and giant planets differ?

- Kepler-444 is one of many stars with terrestrial planets that is over 10 billion a) What do you think the spectral type of Kepler-444 might be? b) How do stars of this spectral type end their lives? c) If evolution followed a similar course on a habitable pranet around a star similar to Kepler-444, it would be 5 billion years more advanced than we are. Let’s try to project our future and see what happens. In particular, suppose our civilization gets motivated enough to colonize another planet. Kepler indicates that most stars have potentially habitable (and colonizable) planets, so roughly how far away is the typical “nearest" planet? d) The New Horizons probe on its way to Pluto took 9 years to travel 30 AU. If we could send colony ships with the same average speed, roughly how long would it take to reach the typical nearest planet? уears old.arrow_forwardIn the context of the giant planets and the conditions in their interiors, what is meant by “rock” and “ice”?arrow_forwardWhich of the following statements is correct? a. The formation of planets stopped because the solar nebula got cooler c. The formation of planets stopped because the solar nebula ran out of planetesimals d. The formation of planets stopped because the solar nebula spinning was slowing down e. The formation of planets stopped because the young Sun's strong solar wind swept away material not yet accreted onto the planetsarrow_forward
