Warm-up
NOT TO SCALE3 spheres. Moon is in the middle, and is the smallest. Sun is the largest. 2 dotted lines extend from Earth at the same point, hit the edges of Moon, and then hit the edges of Sun. The dotted lines form a triangle shape with a curved bottom between Earth and Moon, and this shape is darkened.
The diameter of the sun is 1,391,000 km. The diameter of the moon is 3,475 km. The distance from Earth to the sun is 149,600,000 km.
How far would the moon have to be from Earth for the moon to appear the same size as the sun?
