d. Diameter of the Sun I h d Standing on the beach at sunset, you extend the tip of your finger at your full arm length from your face, covering the Sun. Upon moving your finger around, you find that only about half of its width is needed to completely cover the Sun's diameter. You measure your finger width to be 0.5 inches. You know your arm length to be 28.0 inches You have be told that the Sun is approximately 93 million miles away. Use this information to determine the approximate diameter of the Sun, filling in the table below with the proper quantities measure in meters. 1=½ finger width X Arm length g = eye level d = object height A = angle from eye f= object height from h= Diameter of the Sun %3D %3D distance 93x10 mi level to top of eye level object OR 1.023 0127m

hding Light Years 26.1 How far is it from Los Angeles to New York? Pretty far, but it can still be measured in miles or kilometers. How far is it from Earth to the Sun? It's about one hundred forty-nine million, six hundred thousand kilometers (149,600,000, or 1.496 x 10 km). Because this number is so large, and many other distances in space are even larger, scientists developed bigger units in order to measure them. An Astronomical Unit (AU) is 4:496x 108 km (the distance from Earth to the sun). This unit is usually used to measure distances within our solar system. To measure longer distances (like the distance between Earth and stars and other galaxies), the light year (ly) is used. A light year is the distance that light travels through space in one year, or 9.468 x 1012 km. 28.1 n the in tem. EXAMPLES 1. Converting light years (ly) to kilometers (km) Earth's closest star (Proxima Centauri) is about 4.22 light years away. How far is this in kilometers? Explanation/Answer: Multiply…
