bdistances from the Earth to the farthest planets and stars

dzodiac signs

ব্যাখ্যা

Ancient astronomers (early "astrologers") could not physically reach celestial bodies, so they used angle measurements and trigonometric ratios to calculate the vast distances to distant planets and stars. This indirect measurement of inaccessible distances is the classic early application of trigonometry.
