SOHO

SOHO is a joint ESA and NASA solar observatory that studies the Sun from its deep interior through the visible surface, corona, and solar wind. Its uninterrupted view from the Sun-Earth L1 region also supports space-weather monitoring and an exceptionally productive search for sungrazing comets.

Description
SOHO is a joint ESA and NASA solar observatory that studies the Sun from its deep interior through the visible surface, corona, and solar wind. Its uninterrupted view from the Sun-Earth L1 region also supports space-weather monitoring and an exceptionally productive search for sungrazing comets.
Destination
Elliptical Lissajous orbit around the Sun–Earth L1 point, approximately 1.5 million km from Earth with an approximately six-month period, for studying the Sun from its interior through the corona and solar wind and monitoring space weather
Launch Site
Outcome
SOHO remains active after three decades, greatly exceeding its original two-year mission. It has built a long record of solar structure and activity, supported operational space-weather forecasting, and discovered more than five thousand comets.
