Can A Laser Pointer Reach The Moon. This size laser for astronomy is ideal for pointing to. The typical red laser pointer is about 5 milliwatts, and a good one has a tight enough beam to actually hit the moon—though it'd be spread out over a large fraction of the surface when it got there.
You Ain't Goin' Nowhere an imagined geography from youaintgoinnowhere.wordpress.com
This is about the thickness of an orange peel. This makes a little bit of sense because you will notice that the sunlight bathes the moon in a large amount of light. The power of a normal red laser pen is 5 mw.
How Long Would It Take A Laser To Reach The Moon?
When we fire a powerful laser pointer at one of the planets. Not if we use regular laser pointers. If the quality is good enough, the laser can hit the moon all the way.
The Apollo Mission (And Two Soviet Landers) Placed A Retroreflector On The Moon, Which Is An Efficient Reflector That Can Reflect The Laser Beam Back To Itself Like A Road Reflector.
The atmosphere would distort the beam a bit, and absorb some of it, but most of the light would make it. First of all, tight as they are, laser beams spread over distance, too. This is about the thickness of an orange peel.
