(671294) 2014 JO25

It is also a potentially hazardous asteroid due to its sufficiently large size (an absolute magnitude brighter than 22), and its Earth-MOID (see below) of less than 0.05 AU.

[8] Based on a generic magnitude-to-diameter conversion, 2014 JO25 measures approximately 720 m in diameter, using an absolute magnitude of 18.1 and assuming an albedo of 0.20, which is typical for stony asteroids.

[3] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.20 and calculates a diameter of 818 meters based on an absolute magnitude of 17.8.

[4][9] The 2017 radiometric observations at Arecibo and Goldstone also gave a rotation period of approximately 4.5 hours.

[9] Also in April 2017, a rotational lightcurve of this asteroid was obtained from photometric observations by Brian Warner at the Palmer Divide Station (U82) in California.
