In the present paper, we efficiently solve the two-body problem for extreme cases such as those with high eccentricities. The use of numerical methods, with the usual variables, cannot maintain the perihelion passage accurately. In previous articles,

From 1998, the International Astronomical Union (IAU) adopted a new Celestial Reference System: the International Celestial Reference System (ICRS). The first optical materialization was the Hipparcos catalogue, defining the Hipparcos Celestial Refer

The orbital motion around a central body is an interesting problem that involves the theory of artificial satellites and the planetary theories in the solar system. Nevertheless some difficult situations appear while studying this apparently simple p

This paper aimed to address the study of a new family of anomalies, called natural anomalies, defined as a one-parameter convex linear combination of the true and secondary anomalies, measured from the primary and the secondary focus of the ellipse,

The total solar eclipse on July 29, AD 1478, went unnoticed by most of Europe. Although several scholars accurately predicted it, very few observations made by professional astronomers have survived, and these contain very little relevant information

It is a long time since the last comprehensive compilation of meteoric observations from medieval European sources was published. Since then, the advances in information technology, search engines and, above all, the emergence and development of the

The eclipse of a.d. 1239 June 3 was observed at no less than 10 sites in Europe, but the one from a.d. 1354 September 17 was observed only from two European sites. In this paper, we present several new references for the a.d. 1239 and a.d. 1354 solar
