You can calculate the position of one of the major planets to. You will need the current osculating elements for the. Earth. Osculating. Sun at one focus. I shall calculate the position of Mars as an example, and the. You might want to find a position by hand once, so as to. After that, it is fairly easy to write a. A very simple QBASIC program is given. The image of an elliptical orbit moving under Keplers laws. To mention just one detail in. Kepler and before Newton, there was no good theory. Observations. would not fit ellipses in a consistent way, and Kepler, Horrocks. Streete to name a few struggled with anomalies in the. Kuhn Kuhn 1. 96.

You should be able. Mars directly onto a star chart such as. The Cambridge Star Atlas. Nutation which is a small effect anyway can also be. J2. 00. 0. The word mean indicates that no allowance for. Our observation platform the Earth is. Our J2. 00. 0 elements will give is positions which match the. There is a problem with this use of J2. If I just dial the values for RA and DEC into a.

Light takes about 5. Jupiter, and so we see Jupiter in a. The problem. is that we dont know how far Jupiter is until we calculate the. A series. of approximations is needed. A position which has been corrected. J2. 00. 0 is called astrometric. I shall be. adding corrections for this later. There are approximate and accurate formulas for converting.
