Atlast.... PhewwW It tuk me three weeks to calculate this.. Some information about our own earth.. Mass (10 24 kg) 5.9726 Volume (10 10 km 3 ) 108.321 Equatorial radius (km) 6378.1 Polar radius (km) 6356.8 Volumetric mean radius (km) 6371.0 Core radius (km) 3485 Ellipticity (Flattening) 0.00335 Mean density (kg/m 3 ) 5514 Surface gravity (m/s 2) 9.798 Surface acceleration (m/s 2) 9.780 Escape velocity (km/s) 11.186 GM (x 10 6 km 3 /s 2 ) 0.3986 Bond albedo 0.306 Visual geometric albedo 0.367 Visual magnitude V(1,0) -3.86 Solar irradiance (W/m 2) 1367.6 Black-body temperature (K) 254.3 Topographic range (km) 20 Moment of inertia (I/MR 2 ) 0.3308 J2 (x 10 -6 ) 1082.63 Number of natural satellites 1 Planetary ring system No Orbital parameters Semimajor axis (10 6 km) 149.60 Sidereal orbit period (days) 365.256 Tropical orbit period (days) 365.242 Perihelion (10 6 km) 147.09 Aphelion (10 6 km) 152.10 Mean orbital velocity (km/s) 29.78 Max. orbital velocity (km/s) 30.29 Min. orbital velocity (km/s) 29.29 Orbit inclination (deg) 0.000 Orbit eccentricity 0.0167 Sidereal rotation period (hrs) 23.9345 Length of day (hrs) 24.0000 Obliquity to orbit (deg) 23.44 Earth Mean Orbital Elements (J2000) Semimajor axis (AU) 1.00000011 Orbital eccentricity 0.01671022 Orbital inclination (deg) 0.00005 Longitude of ascending node (deg) -11.26064 Longitude of perihelion (deg) 102.94719 Mean Longitude (deg) 100.46435 North Pole of Rotation Right Ascension: 0.00 - 0.641T Declination : 90.00 - 0.557T Reference Date : 12:00 UT 1 Jan 2000 (JD 2451545.0) T = Julian centuries from reference date Terrestrial Magnetosphere Dipole field strength: 0.3076 gauss- Re 3 Latitude/Longitude of dipole N: 78.6 degrees N/70.1 degrees W Dipole offset (planet center to dipole center) distance: 0.0725 Re Latitude/Longitude of offset vector: 18.3 degrees N/147.8 degrees E Note: Re denotes Earth radii, 6,378 km Terrestrial Atmosphere Surface pressure: 1014 mb Surface density: 1.217 kg/m 3 Scale height: 8.5 km Total mass of atmosphere: 5.1 x 10 18 kg Total mass of hydrosphere: 1.4 x 10 21 kg Average temperature: 288 K (15 C) Diurnal temperature range: 283 K to 293 K (10 to 20 C) Wind speeds: 0 to 100 m/s Mean molecular weight: 28.97 g/mole Atmospheric composition (by volume, dry air): Major : 78.08% Nitrogen (N 2 ), 20.95% Oxygen (O 2 ), Minor (ppm): Argon (Ar) - 9340; Carbon Dioxide (CO 2 ) - 400 Neon (Ne) - 18.18; Helium (He) - 5.24; CH 4 - 1.7 Krypton (Kr) - 1.14; Hydrogen (H 2 ) - 0.55 Numbers do not add up to exactly 100% due to roundoff and uncertainty Water is highly variable, typically makes up about 1%
