45 Fun Things to Do When It's Way Too Hot Outside (and You Don't Have a Pool)

SOLVED: Consider a bright star in our night sky. Assume its distance from Earth is 31.0 light-years (ly) and its power output is 4.00 × 10^28 W, about 100 times that of the Sun. One light-year is the distance traveled by light through a vacuum in one year. a) Find the intensity of starlight on Earth. b) Find the power of the starlight the Earth intercepts. (The radius of Earth is 6.38 × 10^6 m.)

SOLVED:The star 61 Cygni, sometimes called Bessel's Star (after Friedrich Bessel, who measured the distance from Earth to the star in 1838 ), is a star in the constellation Cygnus. (a) If 61 Cygni is 11.14 light-years from Earth and 1 lightyear is about 5.9 trillion miles, how many miles is 61 Cygni from Earth? (b) The mean distance from Earth to the Sun is 93,000,000 miles. What is the parallax of 61 Cygni?
