R. Roka,M. Hermann,B. Niederle,E. Wenzle find that it is not its nearest neighbour, the Earth, that has the greatest effect, but the more distant Sun. Although gravitational force decreases as the square of the distance, the Sun’s gravity exceeds that of the Earth, because of its far greater mass.

What positive advantages are there in using one’s own computer, when one can obtain all the most important data required for observing, fully as accurately, in one o

Ecliptic coordinates refer the position of a point to the plane of the Earth’s orbit, while equatorial coordinates are measured relative to the position of the Earth’s or celestial equators. The

As such an observer (without being aware of it) takes part in the Earth’s daily rotation, it appears as if the Sun, Moon, and stars follow large arcs across the sky from East t

The five or six orbital elements describe the orbit in space and time in a significantly shorter form than a long listing of positions. In general, the orbital elements of newly discovered comets are published by the International A
