Appendix D: Astronomical Data

This table has 5 columns and two header rows. The first header row labels each column as follows: Celestial Object, Mean Distance from Sun in million kilometers, Period of Revolution in d equal to days or y equal to years, Period of Rotation at Equator, Eccentricity of Orbit. Each row describes 1 celestial object as follows: Sun, blank, blank, 27 d, blank; Mercury, 57.9, 88 d, 59 d, 0.206; Venus, 108.2, 224.7 d, 243 d, 0.007; Earth, 149.6, 365.26 d, 23 h 56 min 4 s, 0.017; Mars, 227.9, 687 d, 24 h 37 min 23 s, 0.093; Jupiter, 778.4, 11.9 y, 9 h 50 min 30s, 0.048; Saturn, 1426.7, 29.5 6, 10 h 14 min, 0.054; Uranus, 2871.0, 84.0 y, 17 h 14 min, 0.047; Neptune, 4498.3, 164.8 y, 16 h, 0.009; Earth’s Moon, 149.6 parentheses 0.386 from Earth parentheses, 27.3 d, 27.3 d, 0.055. The next row is the second header which contains the columns Celestial Object, Equatorial Diameter in kilometers, Mass with Earth equal to 1, Density in grams per cubic centimeter. Each row describes 1 celestial object as follows: Sun, 1392000, 333000, 1.4; Mercury, 4879, 0.06, 5.4; Venus, 12104, 0.82, 5.2; Earth, 12756, 1.00, 5.5; Mars, 6794, 0.11, 3.9; Jupiter, 142984, 317.83, 1.3; Saturn, 120536, 95.16, 0.7; Uranus, 51118, 14.54, 1.3; Neptune, 49528, 17.15, 1.6; Earth’s Moon, 3476, 0.01, 3.3.
