Universal Gravitational Constant: G = 6.674 x 10-11 m^2/(kg∙s^2 )
A star you are observing from the Earth is found to have a parallax of 0.5 arcsec. How far away is this star?
What is the force of gravity between you and the white dwarf Sirius B? The mass of Sirius B is about 1.02 times the Sun. Assume its radius is same as the Earth. How does this result compare to the force of gravity between you and the Earth which you calculated in Homework 5? What do you think will happen to you if you visited such a place?
