Solar system | Definition, Planets, Diagram, Videos, & Facts
Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with more than 400 known planetary satellites; many asteroids, some with their own satellites;
Analemma
Globes of the Earth often display an analemma as a two-dimensional figure of equation of time ("sun fast") vs. declination of the Sun. The north–south component of the analemma results
Analemma Calculator – Equation of Time and Sun Position
The calculator shows two synchronized visualizations: the classic analemma figure-8 (solar declination vs equation of time) and a separate equation of time graph throughout the year.
NOAA Solar Position Calculator
Time of day for the calculation can be changed in the same way. Hit the "Calculate Solar Position" button. Once the calculations are complete, you may use your browser''s "Print" function to

SPA Calculator
Compute the solar position from time and place using NLR''s SPA.
Analemmas And The Equation Of Time: Why The
The reason for the figure of eight analemma is the difference between the actual position of the Sun in the sky and the mean solar time
Analemmas And The Equation Of Time: Why The Path Of The
The reason for the figure of eight analemma is the difference between the actual position of the Sun in the sky and the mean solar time measured by your own clock.

PHY 445/515: Coordinate Systems
Azimuth is measured in degrees East of North. There are other systems, but they are less commonly used. One such system is the supergalactic system. A number of these sysemts

Solar coordinate systems
The Carrington heliographic coordinate system, established by Richard C. Carrington in 1863, rotates with the Sun at a fixed rate based on the observed rotation of low-latitude sunspots.
