... This paper discuss a polynomial approximation to T for the range of 1620 to 2000 AD published by Jean Meeus and Larry Simons and gives a modified version of this approximation which is much more accurate. ... For this purpose Jean Meeus and Larry Simons published a paper in 2000, which gives a set of polynomial approximation of T for the range of years 1620 to 2000 (Meeus 2000). ... Using these empirical formulae we can calculate the value of T at any instant of the year for the range 1620 to 2000...

November 2006 Astronotes 1 Candles in the Dark Image Credit: Wikipedia.org By Colin Johnston, Science Communicator Since the mid-ninteenth century astronomers have used the principle of parallax to measure the distance to other stars. ... How then can we tell, for example, that M31, the galaxy in Andromeda, is 2.2 million light years away? It would be straight-forward to tell how far away a star was if it was exactly the same brightness as our own Sun. ...
