Astronomical Values

Celestial Bodies

Note 1: The planetary magnitudes are calculated in a very crude manner. For details, click here.

Note 2: The chart shows West on the right, East on the left, North is at the top, and South is at the bottom. This the opposite of most maps, because they show the Earth looking down, while my chart shows the sky looking up.

Note 3: The units for all of the tide gradients are pico inverse squared seconds. (/sec/sec). The percentage is that of a "perfect" perigean situation of a solar eclipse happening exactly over the equator simultaneously with both terran perihelion and lunar perigee. A is the absolute value of the vector sum of the lunar and solar gravity gradients. It is the maximum tidal gradient possible, i.e. directly beneath the apparent position of the above-described vector it is the strength of the gradient straight up. At the selected earth position, the strength is S, which is resolved into geocentric vectors V (Vertical), and H (Horizontal).
