SUMMARY
Venus, Mars, and Saturn are converging in the Leo Constellation at the end of the month. To calculate their Right Ascension (RA) and Declination (Dec), one must utilize data from the JPL Horizons system and the planetary elements file available at the JPL website. The calculation involves determining the planets' positions relative to the Sun, accounting for Earth's position, and converting to geocentric coordinates while correcting for the equation of time. Detailed methodologies can be found on resources like Stargazing.net.
PREREQUISITES
