Effect of Jupiter and Venus on the Sun, 1743 - 1756

Reference Code: GBR/0180/RGO 4/68

Scope and Contents

Computations on the effect of Jupiter and Venus on the Sun's place.

1. Computations on the inequality of the Earth, produced by Jupiter and Venus, on Johann Mayer's theoretical position compared with two sets of observations, 7 June 1745 - 29 December 1751 and 4 May 1751 - 22 March 1756.

2. New errors in the solar table, 14 January 1743 - 25 April 1756.

3. Corrections to the places of the Sun's apogee by observations near the apogee and perigee.

4. Tables for the equation of the Sun's centre and calculations of the eccentricity of the Earth's orbit, with tables.

5. The maximum of the equations of Jupiter and Venus determined. There is also the maximum of the lunar equation that disturbs the Sun's motion, 1743-1756.

6. New errors in the solar table for determining the lunar equation, 1743-1756.

7. The maximum of Jupiter's equation determined from errors of the solar tables, 1743-1755.

8. The maximum of Venus' equation determined from errors of the solar tables, 1743-1755.

9. Arguments of the two small equations affecting the Sun's place.

10. Annual results and observations of the solar equation, 1744-1755.

11. Tables for finding the Sun's anomaly for every day of the year.
