How the Calculator Works

The Star Proper Motion Calculator uses the following scientific formula to compute proper motion:

Total Proper Motion (μ):

μ = √(μ_RA² + μ_Dec²)

Where:

• μ_RA = (RA₂ - RA₁) / Δt * cos(Dec₁)
• μ_Dec = (Dec₂ - Dec₁) / Δt
• RA₁, RA₂ = Initial and final right ascension (degrees)
• Dec₁, Dec₂ = Initial and final declination (degrees)
• Δt = Time difference in years between the two observation dates

The calculator converts the input coordinates (in degrees) and computes the proper motion components in arcseconds per year. The cosine term in the RA component accounts for the spherical geometry of the celestial sphere, ensuring accurate results. The time difference is calculated automatically based on the input dates.

This methodology is based on standard astronomical practices, as described in resources like the Star Proper Motion Wikipedia page. The calculator ensures precision by using JavaScript's built-in math functions and date handling capabilities, minimizing errors in the computation process.
