Near-Earth object / ID: 2004034
4034 Vishnu is a near-Earth object of the APO orbit class — Near-Earth asteroid orbits which cross the Earth’s orbit similar to that of 1862 Apollo. Radar and photometric estimates put it between 530m - 1.2km across. It has been followed since 1986-08-02 across 1333 recorded observations. Its next approach to Earth is 2037-Mar-28 10:31, passing at 69.864 LD. JPL classifies it as a potentially hazardous asteroid, a label driven by its size and how close its orbit comes to ours — not by a predicted impact.
