| The smallest detail visible through Earth based telescope is about 1 second of arc
in diameter? What size is this on Earth's moon?
I would like to compare notes my answer
I came up with
1/2 a degree and 1740kilometers
Am I correct????
Moon's Diameter is about 3460. It is about the distance of 390000Km from earth. One arc second is one divided by3600degree. So using simple trigonometry calculate the distance. Moon is about 30 arc minute average. That is 30x60 Arc seconds.
That is 3460Km is 30 arc minute from that also you can calculate the distance for one arc second
