A spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity.Spacetime diagrams can show the geometry underlying phenomena like time dilation and length contraction without mathematical equations.
The Quitsato Sundial is a cultural-tourist place located at La Mitad Del Mundo, near to Cayambe, 47 km north of Quito, Ecuador.It was built in 2006 and inaugurated in 2007 as an independent, non-profit project in a 24,756 ft 2 (2,300 m 2) area.
A Sun-synchronous orbit is useful for imaging, reconnaissance, and weather satellites, [4] because every time that the satellite is overhead, the surface illumination angle on the planet underneath it is nearly the same.
Earth at seasonal points in its orbit (not to scale) Earth orbit (yellow) compared to a circle (gray) Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi), or 8.317 light-minutes, [1] in a counterclockwise direction as viewed from above the Northern Hemisphere.
The solar zenith angle is the zenith angle of the sun, i.e., the angle between the sun’s rays and the vertical direction.It is the complement to the solar altitude or solar elevation, which is the altitude angle or elevation angle between the sun’s rays and a horizontal plane.
Shifts in the oceanic temperature distribution can cause significant weather shifts, such as the El Niño–Southern Oscillation. [ 208 ] The abundance of water, particularly liquid water, on Earth's surface is a unique feature that distinguishes it from other planets in the Solar System .
Andreas Cellarius's illustration of the Copernican system, from the Harmonia Macrocosmica. Heliocentrism [a] (also known as the heliocentric model) is a superseded astronomical model in which the Earth and planets orbit around the Sun at the center of the universe.
In geodesy, the figure of the Earth is the size and shape used to model planet Earth.The kind of figure depends on application, including the precision needed for the model.
