    The Solar Terrestrial Relations Observatory, or STEREO, mission employs two nearly identical space-based observatories to provide the stereoscopic measurements to study the sun. With a pair of viewpoints, scientists are able to see the structure and evolution of solar storms as they blast from the Sun and travel out through space.

    STEREO B (Solar TErrestrial RElations Observatory – Behind) made its closest pass to L 5 in October 2009, on its orbit around the Sun, slightly slower than Earth. [14] The Spitzer Space Telescope is in an Earth-trailing heliocentric orbit drifting away c. 0.1 AU per year. In c. 2013–15 it has passed L 5 in its orbit.

    Solar Terrestrial Relations Observatory (STEREO) mission was launched in October 2006. Two identical spacecraft were launched into orbits that caused them to (respectively) pull further ahead of and fall gradually behind Earth. This enables stereoscopic imaging of the Sun and solar phenomena, such as coronal mass ejections. [6] [7]
