Recently my Catalina Sky Survey teammates Carson Fuls and Jess Johnson discovered an asteroid which comes close enough and is large enough be be classified as a Potentially Hazardous Asteroid. It was subsequently observed by telescopes in New Zealand, Australia, Italy, Arizona, Pennsylvania, and Illinois and given the name 2015 DH155. Fortunately, its orbit never brings it closer than about 16 times the Moon's distance from planet Earth.
