where d is the distance in parsecs, and p is the parallax angle in arcseconds.

Express r_a in terms of r_p and e: r_a = r_p * (1 + e) / (1 - e) spherical astronomy problems and solutions

A star catalog from 1950 (Epoch B1950) won't match a telescope's position in 2024 (Epoch J2000). where d is the distance in parsecs, and

To solve almost any problem in this field, you need these three identities: The Sine Rule: The Four-Parts Formula: (Where are the sides—measured as angles—and are the opposite angles.) Problem 1: Converting Horizontal to Equatorial Coordinates The Challenge: An observer in London (Latitude N) observes a star at an altitude ( 40∘40 raised to the composed with power and an azimuth ( 120∘120 raised to the composed with power spherical astronomy problems and solutions
