Threatening Object?

Minor planet 2014 JO25 made a "close" approach to Earth on April 19, 2017, passing within 2 million km of our planet. That's a very safe margin, but any object that crosses Earth's orbit and is as large as this one has the potential to unleash regional devastation should it ever collide with us. Good reason to keep it under study. This pic is my (successful?) attempt to get a shot of the asteroid on the evening before closest approach. Among the many star trails which accumulated during the untracked exposure is one at a slight angle, indicating motion against the starry background. 60 sec exposure at ISO400, f2.8, using a Panasonic FZ-200 camera on tripod -- taken from my suburban back yard. Contrast and gamma enhanced. Cropped from original frame.
