File:Orbit Sirius B arcsec.png

Summary

Description
English: Trajectory of Sirius B relative to Sirius A as seen from Earth and as seen from above. The axis is scaled in arcseconds.

The orbital parameters this plot is based on are taken from van den Bos (1960; used now in en.wikipedia:Sirius). The graph has been created with gnuplot based on data generated by solving Kepler's equation.

Notes: 1. The time stamps refer to the motion as seen from Earth, i.e. delayed with respect to the true motion by the travel of light by about 8.7 years. North is down, as usual in many astronomical charts. 2. The points refer to steps of 1/50 of an orbit rather than to exact 1-year steps (which would be 1/50.09 of an orbit).
