Presentation transcript:

The EARTH is 93 Million Miles from the SUN.

Distances in our Solar System are measured in ASTRONOMICAL UNITS (AU).

A LIGHT YEAR IS THE DISTANCE LIGHT TRAVELS IN ONE YEAR!!! LIGHT YEARS distance!!! IS A MEASURE OF A LIGHT YEAR IS THE DISTANCE LIGHT TRAVELS IN ONE YEAR!!!

Scientist use LIGHT YEARS because STARS are too far away from each other to use… feet feet meters inches kilometers astronomical units miles

One LIGHT YEAR is 10,000,000,000,000,000 meters or 16 10 X 10 meters Five Light Years = 5 x 1016 meters

It takes 43 (human) years for the light from this star to reach earth! 43 Light Years from EARTH It takes 43 (human) years for the light from this star to reach earth! By the time you see the light 43 years have passed. The light was created before most of your parents were born.
