Web10 feb. 2024 · The astronomical unit distance between the star and the Sun can be calculated using the trigonometric function. As per the given data: distance from Earth to the Sun (P) = 1 AU θ = 0.00001389 degrees From tanθ: tanθ = P/B {P = perpendicular and B = base} From the diagram: tanθ = 1/d tan (0.00001389) = 1/d d = 1/tan (0.00001389) d = … WebCepheid variables can be used to measure distances from about 1kpc to 50 Mpc. For example, if an astronomer observed a Cepheid star with period of 34 days, comparing to previously measured Cepheids, its absolute magnitude is -5.65. If its apparent magnitude was +23.0, the astronomer could use the distance modulus equation: m - M = 5 log d - 5
