SDSU What if The Sun Had Been Born in A Tertiary System Discussion Questions
Description
Questions
1. Suppose we wanted to send a satellite to orbit Pluto at 40 AU away from the Sun to measure the parallax of stars…describe at least 3 advantages and 3 disadvantages of measuring parallax with a satellite near Pluto versus measuring parallax with a telescope on Earth’s surface.
2. We have encountered objects that have entered our solar system from other solar systems (‘Oumuamua is one famous example…feel free to research this object if you have never heard of it before). What if our solar system encountered another star 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)?
