WebGravitational force F_g F g is always attractive, and it depends only on the masses involved and the distance between them. Every object in the universe attracts every other object with a force along a line joining them. The equation for Newton’s law of gravitation is: F_g = \dfrac {G m_1 m_2} {r^2} F g = r2Gm1m2. WebDec 17, 2024 · The gravitational parameter (symbol of a body (normally a planet, moon or star) is a value which represents the strength of its gravitational pull. This value is used in calculations involving other bodies which orbit it. For a body with mass and the universal gravitational constant , Contents 1 Justification[1]

In other words, μ = GM = 398600.4418 km3/s2 Unfortunately, because the value of G is not known with a high degree of certainty, this uncertainty level carries over to the Standard Gravitational Parameter. crystal hatchet runescape 3
Earth Gravitational Constant (`mu`) : `m^3`/`sec^2`
In celestial mechanics, the standard gravitational parameter μ of a celestial body is the product of the gravitational constant G and the mass M of the bodies. For two bodies the parameter may be expressed as G(m1+m2), or as GM when one body is much larger than the other. For several objects in the Solar … See more Small body orbiting a central body The central body in an orbital system can be defined as the one whose mass (M) is much larger than the mass of the orbiting body (m), or M ≫ m. This approximation is standard for planets … See more Geocentric gravitational constant GMEarth, the gravitational parameter for the Earth as the central body, is called the geocentric gravitational constant. It equals (3.986004418±0.000000008)×10 … See more • Astronomical system of units • Planetary mass See more A non-rotating perfect sphere of uniform mass density, or whose density varies solely with distance from the centre (spherical symmetry), would produce a gravitational field of uniform magnitude at all points on its surface. The Earth is rotating and is also not spherically symmetric; rather, it is slightly flatter at the poles while bulging at the Equator: an oblate spheroid. There are consequently … WebEarth (aka geocentric gravitational constant): 3.986004418 × 10 5 km 3 s-2 Moon : 4.9028695 × 10 3 km 3 s -2 A body's standard gravitational parameter depends entirely … crystal haven yarm
