Textbook Question
Chapter 3, Problem 54IF
Rocks from Other Solar Systems. Many “leftovers” from planetary formation were likely ejected from our solar system, and the same has presumably happened in other star systems. Given that fact, should we expect to find meteorites, or even entire planets, that come from other star systems? How rare or common would you expect them to be? (Be sure to consider the distances between stars.) Suppose that we did find a meteorite identified as a leftover from another stellar system. What could we learn from it?

If you could visit another planetary system while the planets are forming, would you expect to see the condensation sequence at work, or do you think that process was most likely unique to our Solar System? How do the properties of the extrasolar planets discovered so far affect your answer?
Do you expect the most planetary system in the Universe have analogs to our Solar System’s asteroid belt and Kuiper Belt? Would all planetary systems show signs of an age of heavy bombardment?
If the solar nebula hypothesis is correct, do you think there are more planets in the Universe than stars? Why or why not?
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
1) How massive would Earth had been if it had accreted hydrogen compounds in addition to the sme properties listed in table 7.1? (Assume the same properties of the ingredients as listed in the table)
2) Now imagine that Earth had been able to capture hydrogen and helium gas in the same proportions as listed in the table. How massive would it have been?

Is it same or different for all planets in the Universe? Explain the reasonarrow_forwardIn Table 2, there is a list of 15 planets, some of which are real objects discovered by the Kepler space telescope, and some are hypothetical planets. For each one, you are provided the temperature of the star that each planet orbits in degrees Kelvin (K), the distance that each planet orbits from their star in astronomical units (AUs) and the size or radius of each planet in Earth radii (RE). Since we are concerned with finding Earth-like planets, we will assume that the composition of these planets are similar to Earth's, so we will not directly look at their masses, rather their sizes (radii) along with the other characteristics. Determine which of these 15 planets meets our criteria of a planet that could possibly support Earth-like life. Use the Habitable Planet Classification Flow Chart (below) to complete Table 2.

If a transit of the Earth across the Sun were viewed by a very distant observer in the Earth’s orbital plane, how long would the transit last?[Hint:You will need the orbital velocity of the Earth,vorb= 30km s−1.]arrow_forwardImagine a trans-Neptunian object with roughly the same mass as Earth but located 50 AU from the sun. a) based on the solar nebula theory, what do you think this object would be made of and why? b) on the basis of speculation, assume a reasonable density for this object and calculate its diameter in units of Earth radii.arrow_forwardWhat is a biomarker?

- In the Star Wars movie Star Wars Episode VI: Return of the Jedi, a key battle takes place on the inhabited “forest moon” Endor, which supposedly orbits around a gas giant planet. From what you have learned about planets and moons of the solar system, why would this be an unusual situation?arrow_forwardExoplanets in eccentric orbits experience large temperature swings during their orbits. Suppose you had to plan for a mission to such a planet. Based on Kepler’s second law, does the planet spend more time closer or farther from the star? Explain.arrow_forwardWhen astronomers found the first giant planets with orbits of only a few days, they did not know whether those planets were gaseous and liquid like Jupiter or rocky like Mercury. The observations of HD 209458 settled this question because observations of the transit of the star by this planet made it possible to determine the radius of the planet. Use the data given in the text to estimate the density of this planet, and then use that information to explain why it must be a gas giant.arrow_forward
