Physical characteristics
According to Michael Brown and the Johnston's archive, 2014 EZ51 measures 626 and 770 kilometers in diameter, based on an
mean diameter.[5]
In 2023, a study on
Kepler space telescope found that 2014 EZ51 rotates with a period of 3.2 hours and exhibits a light curve amplitude of 0.145±0.026 magnitudes, which indicates its shape must be elongated.[7]
