**FOCUS**:  Astronomy, Physics, Mathematics, General Science, Math and Science Programming in PHP.\\ 
Each program attempts to open in its own tab.  To exit a program, simply close its tab.\\ 

**Many of the calculators are based on the //NASA / JPL DE405// ephemeris model, used for several years as the basis of the //Astronomical Almanac// published by the //US Naval Observatory.//  It is not entirely obsolete, as it gives reliable computations for several years past and into the future.\\ 
\\ 
The same can be said for the VSOP87 theory.  It is old, but not entirely obsolete and still has some practical applications and is still widely used today.**\\ 

**Some of the more recent calculators are based on the new //JPL Horizons API// and subject to its availability.  These programs are first-generation experiments, since I'm still learning how to apply the API functions remotely. It can be vexing sometimes.**

=====NASA/JPL DE405 Ephemeris Calculators=====
Planetary and lunar ephemeris computations based on the NASA/JPL DE405 (Development Ephemeris Model Version 405) which spans the 600-year period from 1600 to 2200. It used to be the basis of the yearly astronomical almanacs.  It will still have some practical uses for some time yet to come.\\

=====NASA/JPL Horizons API-Based Computations With Optional PHP Source Code=====
**Planetary and Lunar Perigee/Apogee and Earth Perihelion/Aphelion Computations Based On The NASA/JPL Horizons API** \\
\\
We generally think of the moon when we refer to apogee and perigee, but apogee and perigee points can also be applied to the planets as well. The point of closest approach to Earth is the perigee point and the farthest distance is the apogee point of the body in its orbit. \\

Here, the definition of the perigee and apogee points refers to the points where the radial velocity of the body, relative to Earth, equates to 0 (zero), after which, the radial distance trend (numerical sign of sequential difference) reverses.  The points where the radial velocity equates to zero are at the minimum and maximum distance points from Earth.\\
\\ 
When the radial velocity changes sign from positive to negative, the body has reached an apogee point and when the radial velocity changes sign from negative to positive, the body has reached a perigee point.  By this definition, a body, such as the moon or the planet Mercury,  can have more than two perigee/apogee events per calendar year.
