Geometrical Aspects of Venus Transit

TL;DR

This paper presents a geometrical method to determine Earth's distance to Venus and Venus's diameter using transit photos, incorporating orbital and rotational corrections, with results aligning well with established literature values.

Contribution

It introduces a comprehensive geometrical model accounting for orbital and rotational movements to improve measurements during Venus transit.

Findings

Accurate Earth-Venus distance measurement

Venus diameter estimation consistent with literature

Model effectively incorporates orbital and rotational corrections

Abstract

We obtained two astronomical values, the Earth-Venus distance and Venus diameter, by means of a geometrical treatment of photos taken of Venus transit in June of 2012. Here we presented the static and translational modelsthat were elaborated taking into account the Earth and Venus orbital movements. An additional correction was also added by considering the Earth rotation movement. The results obtained were compared with the values of reference from literature, showing very good concordance.
