Students have asked these similar questions
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?

- 15)Based on the information found in modules 2.1 , 2.2 AND 2.3 put the following statements about the formation of the Solar system based on the NEBULAR HYPOTHESIS in the correct order from 1. ‘’OLDEST EVENT’’ (first to form according to the Nebular hypothesis) to 5. ‘’YOUNGEST EVENT’’ (Last to form in the Solar system, based on the sequence of events listed) . • Clusters of molten metals and dust particles stuck together to form rocks • Lighter gases were swept away from center of solar system into outer solar system • One to two proto-planets collide to form our Moon • Mutual gravity caused rocks to come together, eventually to form protoplanets • Heavier rocky material, with metallics with higher melting points are left nearer to sunarrow_forwardFor which of the following reasons (select all that apply), is it useful/important to send rovers to other planetary bodies in our solar system? O a. The engineering innovations developed to produce successful/viable rovers and landers on other planets can help lead to developments in the technology used here on Earth that may have taken far more time to develop without the limitations provided by space travel to foreign worlds. O b. The data collected can help improve our understanding of the evolution/development of our solar system. O. Rovers/landers can be outfitted with various tools and equipment that can be used to inform of us of the geological histories of each of the planets they visit. O d. More direct probes of the planetary surface are possible to detect signs of the building blocks of life. O e. Rock samples can be used to calibrate our estimations of the age of the solar system.arrow_forwardWhat is the best way to determine if a exoplanet has life inside it? Group of answer choices Detect the star the exoplanet is orbiting and compare it to the Sun. Detect the exoplanet and determine if it is in the habitable zone of the star. Detect the exoplanet and study the atmosphere of the exoplanet. Detect the exoplanet and determine its age to see if it is similar to the age of the Earth.arrow_forward

Halo stars formed in a different way from disk stars. B. Planets around stars are known to be extremely rare. C. Halo stars formed in an environment where there were few heavy elements to create rocky planets. D. Halo stars do not have enough mass to hold onto planets. Is the answer C? Since halo stars are formed early when the galaxy consisted of mainly hydrogen and helium, there are no heavier elements available to create Earth-like planets so just halo stars are formed?
