NASA, ESA Project Identifies 3,000 Comets Over 20 Years

Over the past 20 years, NASA and the European Space Agency’s Solar and Heliospheric Observatory have identified 3,000 comets that passed near and through the solar system and around the sun. This video uses data from the observatory (known as SOHO) to show comets it has spotted, along with comets discovered by others. The SOHO comets in the video are the ones without names.
