Information about STEREO-A close approach to Earth, August 2023

Solar Orbiter perihelion passage, 3 March 2029

This figure shows the orbital configuration of STEREO Ahead (red) during the perihelion passage of Solar Orbiter (orange) centered on 3 March 2029. The positions of Solar Orbiter are plotted at one day intervals from five days before perihelion to five days after. The sense of motion is counter-clockwise. During this short period, the motions of STEREO and the planets are negligible in the Heliocentric Earth Ecliptic coordinate system which follows Earth's orbital period.

Orbital plot

Note that the projected location of STEREO Behind is also plotted. However, that spacecraft is not currently operational. Follow this link for more information.
