Where is SOHO right now?

Orbital Radar tracks SOHO in real time from NASA JPL Horizons ephemeris data, showing its live distance from Earth and the Sun, current speed and one-way signal delay, updated every 60 seconds. The Solar and Heliospheric Observatory — a joint ESA/NASA sun-watcher stationed at Sun–Earth L1 since 1996. It is the most prolific comet-discoverer in history and a round-the-clock source of coronagraph imagery and space-weather warnings.

How far is SOHO from Earth?

SOHO's distance from Earth changes constantly as both bodies move through the solar system. The live figure — in kilometres and astronomical units (AU), with the matching light-travel (signal) time — is shown at the top of this page and refreshes automatically.

The Sun's Constant Watchman

The Solar and Heliospheric Observatory (SOHO), a joint ESA/NASA mission launched in 1995, has watched the Sun without interruption from Sun–Earth L1 for nearly three decades — far outliving its planned two-year mission. Its instruments monitor the solar interior, the corona and the solar wind, and its coronagraph imagery underpins much of modern space-weather forecasting.

The Greatest Comet Hunter

SOHO has also become the most successful comet discoverer in history, with well over 5,000 comets found — most spotted by volunteers combing through its images online. From L1 it provides the early view of Earth-directed coronal mass ejections that can threaten satellites and power grids.
