Comet Hale Bopp in the Outer Solar System
26.03.2001
Whatever became of Comet Hale-Bopp? The brightest comet in recent years has continued into the outer Solar System and is now further from the Sun than Saturn. To the surprise of many, Comet Hale-Bopp is still active, continuing to spew gas, ice and dust particles out into space.
