The radius of the earth's orbit is 45,000,000 meters. In this state, it would have approximately the same mass as it has now, but its radius would be equal to the radius of the Earth. For example, if you stand at a point on the earth and move around the earth in a straight path, and reach the same point again, then the distance covered by you is the circumference of the earth. r . The Earth's mean radius of curvature at latitude is:[12]:97. Given you're looking for a simple formula, this is probably the simplest way to do it, assuming that the Earth is a sphere with a circumference of 40075 km. 903 mi) at the poles and 6371.

Like a torus, the curvature at a point will be greatest (tightest) in one direction (northsouth on Earth) and smallest (flattest) perpendicularly (eastwest). What happens to the dry ice at room pressure and temperature? Derivation means the action of obtaining something from a source or origin. Definition of radius 1 : a line segment extending from the center of a circle or sphere to the circumference or bounding surface. A partial surface of an ellipsoid gets fitted to the region, in which case the center and orientation of the ellipsoid generally do not coincide with the earth's center of mass or axis of rotation. The reason for keeping those older values was GPS. Tack one end of a piece of string to the top of the stick. [Mass of the earth is 6 x 1024 kg and radius of the earth is 6.4 x 106 m]. Its "up" direction there is shown with a black segment: it is, by definition, perpendicular to the ellipse at that point. ), In geophysics, the International Union of Geodesy and Geophysics (IUGG) defines the Earth's arithmetic mean radius (denoted R1) to be[2], The factor of two accounts for the biaxial symmetry in Earth's spheroid, a specialization of triaxial ellipsoid. The answer would be 695 500 000 m. Wiki User. It is 6356. About Earth radiusThe Earth radius, or even the radius of the world, may be the distance from the middle of our planet towards the surface. Now we know 2 things- 1. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Therefore, the Earth radius isn't constant, but it can be calculated for every location. We know that the acceleration due to gravity is equal to 9.8 m/s2, the Gravitational constant (G) is 6.673 1011 Nm2/kg2, the radius of the Earth is 6.37 106 m, and mass cancels out. Earth, on the other hand, isn't quite a sphere. How far is the center of the Earth in KM? View this answer. [ International Space Station Facts and Figures | NASA Its mean density is 1410 kg/m 3 or 0.255 times the mean density of Earth. The following is a partial list of models of Earth's surface, ordered from exact to more approximate: In the case of the geoid and ellipsoids, the fixed distance from any point on the model to the specified center is called "a radius of the Earth" or "the radius of the Earth at that point". If one point had appeared due east of the other, one finds the approximate curvature in the eastwest direction. Our descriptions of Earths surface must be simpler than reality in order to be tractable.

The first published reference to the Earths size appeared around 350BC, when Aristotle reported in his book On the Heavens(18) that mathematicians had guessed the circumference of the Earth to be 400,000 stadia. For a perfect sphere without any mountains, the distance d from a transmitting antenna to the horizon or the line of sight, or radio horizon, can be calculated from the Pythagorean theorem (see the picture above):. Putting in the numbers, you have Dividing both sides by m1 gives you the acceleration due to gravity: Newton's law of gravitation gives you the acceleration due to gravity near the surface of the Earth: 9.8 meters/second 2. Radius of planet R = 2 x radius of earth = 2 x 6.4 x 10 6 m. G = gravitational constant = 6.67 x 10-11 N m 2 /kg 2.

Since the locations are points on a circle that goes around the Earth, the distance between them can be expressed as an arc measurement on a 360-degree circle. Here x is the circumference of the earth. r What is the radius of Jupiter in meters in scientific notation? Earth Fact Sheet - NASA The Earth is slightly oblate, so its radius in the plane of the equator is a little larger than its radius along the rotational axis. The meridional mean is well approximated by the semicubic mean of the two axes,[citation needed]. a) The diameter of the earth is approximately 1.276 1 0 7 1.276 \times 10^7 1.276107 m in scientific notation. The following equation estimates the ellipsoid radius ( r s ) using flattening ( f ) , geocentric latitude ( s ) , and equatorial radius ( R ) : r s = R 2 1 + [ 1 / ( 1 f ) 2 1 ] sin 2 s . Because these measurements are not done with more sensitive equipment, the radius calculation will be only approximate. The mathematical expressions above apply over the surface of the ellipsoid. When it is measured around the equator, it is40,075 km (approximately, 24,901 miles), whereas, if it measured from the north pole to the south pole it is40,008 km (approximately, 24,860 miles). The radius is more like 6,371 kilometers at the north and south poles. Where K is the Gaussian curvature, Ocean Worlds Resources. Rotation of a planet causes it to approximate an oblate ellipsoid/spheroid with a bulge at the equator and flattening at the North and South Poles, so that the equatorial radius a is larger than the polar radius b by approximately aq. The Bohr model of the atom predicted the radius of the lowest-energy electron orbit. In physics, it is established that the acceleration due togravity, g (in meters/sec 2), at a height h meters abovesea level is given by g(h)= 3.99 *10 14 (6.374* 10 6 + h) 2 where 6.374 * 10 6 isthe radius of the Earth in meters.
