Envisat - Close encounters

The following table lists the upcoming close encounters with all other known orbiting objects for which orbital elements are available (over 16000). Only objects which come within 5 km are included. Please note that the accuracy of these predictions is limited by the accuracy of the latest orbital elements. A position accuracy of approximately 1 km is typical. Click on a row to get more details about the encounter and a graphical representation.
