a point at 30°15′20″ N is the arc that results from an angle of 30°15′20″ at the center of the globe. Astronomical latitude is the angle created by the equatorial plane and a line created by the direction ofgravity(that is, the plumb line) occurring at a given point on Earth...
1.(Physical Geography) distance in degrees east or west of the prime meridian at 0° measured by the angle between the plane of the prime meridian and that of the meridian through the point in question, or by the corresponding time difference. Seelatitude1 ...
Thelatitudeof a point is the angle between the plane of the equator and a line that connects the point to the rotational axis of the planet. The type and value of the latitude depends on the way you define the line. Latitude is positive in the northern hemisphere, reaching a limit of ...
The angle between the plane of the reference meridian and the plane through the polar axis and the normal to the spheroid. It is the astronomical longitude corrected for the prime vertical component of the deflection of the vertical divided by the cosine of the latitude. This is the longitude...
The celestial longitude of the position of a body projected on the celestial sphere when the body is viewed from the center of the earth. (geodesy) At a position on the earth's surface, the angle between the plane of the reference meridian and a plane through the polar axis and a line...
ϕϕ, the angle between the xx-axis and the projection of the position vector on the xyxy plane. These are called polar coordinates.Polar coordinates on a three-dimensional space. Source: Wikimedia 🔎 Learn more about polar coordinates in our polar coordinates calculator. The haversine is ...
AGreat Circleis any circle that is formed by a plane that passes through the center of the Earth. The equator and the circles created by the meridians form Great Circles. The shortest line between two points on the Earth's surface is always the arc of a Great Circle. Because of this, ...
The Earth, which is almost spherical in shape, rotates around its vertical axis. An imaginary line that's parallel to this rotational axis would pass through thenorth and south poles, the northernmost and southernmost points on Earth, respectively. ...
Those have mostly q ∼ 1 AU and short semi-major axis orbits. There is also an equivalent helion source, centered on the position of the Sun (at λ = 360° and β = 0° in the diagram). The dynamic type of a meteoroid orbit follows from its Tisserand parameter. The Tisserand ...
