Small angle equation astronomy
WebbTo determine the physical diameter of Jupiter (on July 26, 2003), we can use what is called the small angle formula: D = linear (physical) diameter α = angular size in arcseconds = … Webbwhere angle θ is in unit of radians, and l and d have the same unit, eg. metres. When the angle is very small, we have θ ≈ sin θ ≈ tan θ (2) which is known as the Small Angle …
