In terms of its orbit, Earth has a very minor eccentricity (approx. 0.0167) and ranges in its distance from the Sun from 147,095,000 km (0.983 AU) at perihelion to 151,930,000 km (1.015 AU) at aphelion. This works out to an average distance (aka. semi-major axis) of 149,598,26...
It has a nominal equator crossing time of 10:30 am local time in descending node. That means that the daytime half of the orbit is directed from northeast to southwest from the North Pole to the South Pole with the sun to the east of the satellite. The relative positions of the ...
Since a hollow planet or star essentially consists of matter in orbit about its central sun, perhaps we could use Kepler's 3rd Law of Planetary Motion to calculate the size of Kolob. Using Kepler's 3rd Law of Planetary Motion, we can use the following formula to calculate orbital radii, ...
Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its single most outstanding feature is that its near-surface environments are the only places in the universe known to harbor life. Learn more ab
Earth has at least five co-orbital asteroids, including3753 Cruithneand2002 AA29. A trojan asteroid companion,2010 TK7, is librating around the leading Lagrange triangular point, L4, in the Earth's orbit around the Sun. The tiny near-Earth asteroid2006 RH120makes close approaches to the Eart...
Earth - Planet, Atmosphere, Geology: The mean distance of Earth from the Sun is about 149,600,000 km (92,960,000 miles). The planet orbits the Sun in a path that is presently more nearly a circle (less eccentric) than are the orbits of all but two of the
Magnetospheres contain considerable amounts of plasma, electrically charged particles in equal proportions of positive charge on ions and negative charge on electrons, from various sources. The main source of plasma in the solar system is the Sun. The solar corona, the upper atmosphere of the Sun...
Earth sun distance in astronomical units (AU). ELEVATION_SOURCE String Elevation model source used for standard terrain corrected (L1T) products. ELLIPSOID String Ellipsoid used in image creation. EPHEMERIS_TYPE String Ephemeris data type used to perform geometric correction. (Definitive or Predictive)...
The pull ofgravityin LEO is only slightly less than on the Earth's surface. This is because the distance to LEO from the Earth's surface is much less than the Earth's radius. However, an object in orbit is in a permanentfree fallaround Earth, because in orbit both thegravitational forc...
Earth-Sun distance (AU). EPHEMERIS_TYPE Identifier to inform the user of the orbital ephemeris type used: "DEFINITIVE" or "PREDICTIVE". If the field is not present, the user should assume "PREDICTIVE". GEOMETRIC_RMSE_MODEL Double Combined RMSE (Root Mean Square Error) of the geometric residu...
