some zoos are compulsive about offering their wild-life near natural conditions.  This is expensive and difficult to achieve.  Are these animals really significantly better off to justify the monies and effort used for these projects?

Consider the following discussions and write a minimum 3 sentence response to each discussion by Wednesday 4/28 at 11:59 P.M.1. Suppose we wanted to send a satellite to orbit Pluto at 40 AU away from the Sun to measure the parallax of stars...name 3 advantages and 3 disadvantages of measuring parallax near Pluto versus measuring on the Earth's surface.2. We have encountered objects that have entered our solar system from other solar systems ('Oumuamua is the most famous example...feel free to research this object if you have never heard of it before). What if our solar system encountered another star system today...what would happen to the Sun in that scenario? Would the Earth survive such an encounter? Why or why not?3. What if the Sun had been born in a tertiary (3 star) system...do you think the Sun would have evolved to be a G star like it is now or would the Sun have evolved into a different type of star? How would planets form in such a system? Where would the habitable zone be located approximately (or would there be one)?
