268 Adorea is a very large main belt asteroid, about Шаблон:Val in width.[1] It was discovered by A. Borrelly on 8 June 1887 in Marseilles. This asteroid is a member of the Themis family[2] and is classified as a primitive carbonaceous F-type/C-type asteroid. It is orbiting the Sun at a distance of Шаблон:Val with an orbital eccentricity (ovalness) of 0.14 and a period of Шаблон:Cvt. The orbital plane is tilted at an angle of 2.44° to the plane of the ecliptic.[3]
From February 23 until March 2, 2006, photometric measurements were taken of the asteroid. These were used to produce a light curve showing a rotation period of Шаблон:Val with a brightness variation of Шаблон:Val in magnitude. This result is consistent with some, but not all previous results. Some studies had suggested a longer rotation period of Шаблон:Val; double the time measured. However, the new data is inconsistent with the longer period.[4]
In May 1979, 268 Adorea was positioned in proximity of the galaxy NGC 4517 and as a bright new light source it was identified as a potential supernova. However, the light was missing from a second photographic plate taken ten days later, and the source was soon identified as the asteroid.[5]
The name refers to adorea liba, the Latin name for spelt cakes produced from meal and salt offered by the Romans as a sacrifice; the name was controversial among astronomers, as all previous asteroids had been named for humans or mythological figures.[6][7]
