307 Nike

307 Nike is a sizeable asteroid of the asteroid belt. It was discovered by Auguste Charlois on 5 March 1891 while working at the Nice Observatory. Charlois named it after the Greek goddess of victory, as well as the Greek name for the city where it was discovered.^[4] Measurement of the light curve of this asteroid in 2000 indicates a rotation period of 7.902 ± 0.005 hours.^[3]

On 2 December 1972, Pioneer 10 made one of its nearest passages of an asteroid when it passed 307 Nike at a distance of about 8.8 million kilometers (0.059 AU) during the spacecraft's pioneering trip through the asteroid belt. No data was collected.^[5]
