Mar 28, 2025 · What is SOHO and how can society benefit from its science? SOHO stands for Solar and Heliospheric Observatory and is a satellite that studies the Sun 24 hours a day, 365 days a year without interruptions.

SOHO moves around the Sun in step with the Earth, by slowly orbiting around the First Lagrangian Point (L1), where the combined gravity of the Earth and Sun keep SOHO in an orbit locked to the Earth-Sun line.

SOHO, the Solar & Heliospheric Observatory, is a project of international collaboration between ESA and NASA to study the Sun from its deep core to the outer corona and the solar wind. SOHO was launched on December 2, 1995.
