Summary
[edit]DescriptionPlano Fundamental de Bessel - Eclipses Solares.png |
Español: Plano Fundamental o Principal de Referencia según Friedrich Wilhelm Bessel para determinar los elementos e instancias de un eclipse solar.
En la figura se describe el Plano Fundamental o Principal de Referencia que pasa por el centro de la Tierra y siendo siempre perpendicular al Eje del Cono de la Sombra Lunar. La línea OZ es paralela a tal Eje y tiene su origen también en el centro de la Tierra, y apunta hacia la esfera celeste, a una Coordenada Ecuatorial Geocéntrica: Ascensión Recta y Declinación del punto Z. Con el fin de determinar las Coordenadas Rectangulares de la Luna y del Sol, el eje de las x va desde el centro de la Tierra hacia el Punto Equinoccial Vernal (Marzo), el eje de las y a 90° del eje de las x y es positivo (+) hacia el punto del Ecuador cuya Ascensión Recta es igual a 90°. El eje de las z es positivo (+) si apunta hacia el hemisferio Norte Celeste. |
