245 Vera

It was discovered by N. R. Pogson on February 6, 1885, in Madras, and was named at the suggestion of his wife. The asteroid is orbiting the Sun at a distance of 3.11 AU with a period of 5.47 years and an eccentricity (ovalness) of 0.19. The orbital plane is tilted at an angle of 5.16° to the plane of the ecliptic. In 1890, Daniel Kirkwood noted that this asteroid shares similar orbital elements with 86 Semele and 106 Dione.

Photometric measurements of this asteroid made during 1980–1981 were used to produce a light curve that demonstrated a rotation period of 14.38±0.03 h with a brightness variation of 0.26±0.01 in magnitude. It is classified as a stony S-type asteroid in the Tholen system. The asteroid has an estimated diameter of 75.95±2.63 km based on near infrared observations.
