Kepler-444 is one of many stars with terrestrial planets that is over 10 billiona) 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 toKepler-444, it would be 5 billion years more advanced than we are. Let’s try to projectour future and see what happens. In particular, suppose our civilization gets motivatedenough to colonize another planet. Kepler indicates that most stars have potentiallyhabitable (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 couldsend colony ships with the same average speed, roughly how long would it take to reachthe typical nearest planet?уearsold.

The star Kepler-444 is over 10 billion years old. We know that the lifetime of our own sun is about ten billion years.Due to its large lifespan, should be lighter in mass to survive more than the lifespan of our own sun. (Larger the mass, less is the lifetime) Part a. It has rocky planets, hence its mass should be not too less either. Hence it should be a K-type star. Part b. A K-type star typically ends up being a red giant at the end of its stellar evolution. Part c. The nearest, potentially colonizable, planet to our earth is Proxima b. It is about 4.22 lightyears away from us. We know that, 1 lightyear≈63241.1 AU∴4.22 lightyears=266877.3 AU Now, Given the average speed is 30 AU in 9 years. ∴266877.3 AU will take: 266877.330×9 years=80063.2 years
