Webb28 maj 2024 · To do this he showed that the maximum angle θ, by which any star is displaced from its mean position, is given by the formula: θ = v/c. where. v is the Earth’s velocity around the Sun; c is the speed of light; θ the angle the star is displaced, measured in radians (2π radians equals 360 degrees, so one radian is approximately 57.3 degrees). WebbMathematically, this can be expressed as: d = S θ where d is the distance, S is the size of the object, and θ is the apparent angular size of the object. You might recognize this as …
