307 Nike is a sizeable asteroid of the asteroid belt. It was discovered by the French astronomer 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]
This object is orbiting the Sun at a distance of 2.91 astronomical unit|AU with an eccentricity of 0.14 with an orbital period of 4.95 years. The orbital plane is inclined at an angle of 6.13° relative to the plane of the ecliptic. It is classified as a carbon-rich C-type asteroid. Infrared measurements yield a diameter of 55 km.[2]
Measurement of the light curve of this asteroid in 2000 indicates a rotation period of 7.902 ± 0.005 hours.[3] A 2016 study revised the rotation period to 11.857±0.001 hours with a brightness variation of 0.20±0.02 in magnitude.[5]
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.[6]
