One method of measuring the distance from the Earth to a star is the parallax method. The idea behind computing this distance is to measure the angle formed between the Earth and the star at two different points in time. The optimal approach is to measure the angle when Earth is on opposite sides of the Sun, as shown in the figure. (a) A star is 5.44 light-years from Earth. If 1 light-year is about 5.9 trillion miles, how many miles is the star from Earth? The star is about miles from Earth. (Simplify your answer. Use scientific notation.)
