245 Vera

Vera (minor planet designation: 245 Vera) is a large Main belt asteroid. It was discovered by N. R. Pogson on February 6, 1885, in Madras,[3] and was named at the suggestion of his wife.[4] 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.[1] In 1890, Daniel Kirkwood noted that this asteroid shares similar orbital elements with 86 Semele and 106 Dione.[5]

    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.[6] It is classified as a stony S-type asteroid in the Tholen system.[2] The asteroid has an estimated diameter of 75.95±2.63 km based on near infrared observations.[7]
