This article introduces classic spherical‑astronomy problems, derives solutions, and provides worked examples you can follow. Topics covered: celestial coordinates, spherical triangles, object rise/transit/set times, hour angle and sidereal time, parallactic angle, conversion between coordinate systems, and small practical problems (angular separation, twilight limits). Equations assume a spherical Earth and standard astronomical conventions. spherical astronomy problems and solutions

You are in New York City (Latitude φ = 40.7° N). You want to observe a star with a Right Ascension of 5h and a Declination (δ) of +20°. If the Local Sidereal Time (LST) is 7h, what are the star’s Altitude and Azimuth? First, find the Hour Angle ( , or 30°. The Solution: Use the fundamental transformation formula: Introduction This was the bread and butter of

The date was November 14th. The wind howled against the aluminum siding, rattling the observation deck, but Elias didn't hear it. He was staring at the clock. You are in New York City (Latitude φ = 40

When he returned, he brought Elara a gift—a brass armillary sphere. “For teaching me,” he said, “that the sky is not a mystery. It’s a sphere — and every problem has a solution if you know which triangle to solve.”
