Textbook Question
Chapter 6, Problem 51EAP
Lucky to Be Here? Considering the overall process of solar system formation, do you think formation of a planet like Earth was likely? Could random events in the early history of the solar sys-tem have prevented our being here today? What implications do your answers have for the possibility of finding planets with Earth-like conditions around other stars? Defend your opinions.

How probable is it that other solar systems will have habitable planets, given what you know about the solar nebula theory? Take a look at NASA's Kepler mission and write a half-page summary of 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?
Considering what you learned from the solar nebula theory, how likely do you think it is to find habitable planets in other solar systems? Visit NASA’s Kepler mission to learn more about this search, and write a ½ page summary on the mission.

- 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_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?

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??^2Eartharrow_forward

- At present, NASA is planning a mission to Europa, to try and assess its habitability. An argument might also be made for Enceladus, however. Let's imagine you had to pick one of those moons to send an uncrewed (i.e. robotic) mission to. The spacecraft will probably orbit the giant planet (Jupiter in the case of Europa, Saturn in the case of Enceladus), and make many flybys of the moon you're studying. Which moon would you pick, and why? The goal here is to briefly discuss the pros and cons of each moon as a target for a mission. You don't even have to have a strong preference either way, just lay out a few pros and cons for each.arrow_forwardAt present, NASA is planning a mission to Europa, to try and assess its habitability.
