how to get the moons diameter in arc seconds

Moons of Saturn Wikipedia
In terms of square arc seconds, the area corresponding to 125,000λ/D diameter dot is for the square side smaller by a factor of π/4, thus given by 99,000λ/D. For λ =0.00055mm (photopic peak), that would give 0.54 square arc second (i.e. square with a 0.54 arc second side) for 100mm aperture , 0.27 arc seconds for 200mm, and so on.... The diameter of the moon can be calculated if the diameter of the Earth is known (as from the experiment The Moon’s distance from Earth). Teaching notes 1 The Greek method of estimating the distance of the Moon is to know the Moon’s diameter and then calculate that it is 110 Moon …

How To Get The Moons Diameter In Arc Seconds

K is a constant with a value of 57.3 for Theta in degrees, 3438 in minutes of arc, 206265 for seconds of arc (the number of the respective units in a radian) The first formula yields image size of the sun and moon as approximately 1% of the effective focal length (Theta/K = 0.5/57.3 = 0.009).

  • Galilean Moons – are the four moons of Jupiter discovered by Galileo Galilee in 1610. Io – With a diameter of 3,642 km it is the 4th largest natural satellite in the solar system. It was named after a priestess who became one of Zeus’ human lovers.
  • A minute of arc, arcminute (arcmin), arc minute, or minute arc is a unit of angular measurement equal to 1 / 60 of one degree. Since one degree is 1 / 360 of a turn (or complete rotation), one minute of arc is 1 / 21 600 of a turn – it is for this reason that the Earth's circumference is …
  • In contrast, the diameter of the Sun on the sky is 32 ~, the diameter on the sky of Venus at inferior conjunction is 1 arc minute,2 the diameter on the sky of Jupiter at opposition is 47 arc seconds,3 and the diameter on the sky of Ganymede, Jupiter's largest moon, at opposition is 1.7 arc seconds.
