Textbook Question
Chapter 6, Problem 26EAP
The nebular theory holds that (a) our solar system formed from the col-lapse of an interstellar cloud of gas and dust. (b) each planet formed from the collapse of its own separate nebula. (c) the planets formed as a result of a near-collision between our Sun and another star.

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
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?

Describe the Nebular Theory. Include A) what it is, B)what happened, and C) at least three lines of evidence to support it.

- 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?arrow_forwardIn a globular cluster, astronomers (someday) discover a star with the same mass as our Sun, but consisting entirely of hydrogen and helium. Is this star a good place to point our SETI antennas and search for radio signals from an advanced civilization? Group of answer choices No, because such a star (and any planets around it) would not have the heavier elements (carbon, nitrogen, oxygen, etc.) that we believe are necessary to start life as we know it. Yes, because globular clusters are among the closest star clusters to us, so that they would be easy to search for radio signals. Yes, because we have already found radio signals from another civilization living near a star in a globular cluster. No, because such a star would most likely not have a stable (main-sequence) stage that is long enough for a technological civilization to develop. Yes, because such a star is probably old and a technological civilization will have had a long time to evolve and develop there.arrow_forwardGiven what you've learned about the solar nebula idea, what do you believe the likelihood is of discovering livable planets in other solar systems?
