778 Theobalda is aminor planet orbiting theSun, in themain asteroid belt. It was discovered byFranz Kaiser on 25 January 1914 and was named after his father, Theobald Kaiser.[2] This is anF-type asteroid[3] that spans ~64 km in girth. It rotates on its axis once every 11.7 hours. 778 Theobalda is orbiting3.19 AU from the Sun with aneccentricity (ovalness) of 0.25 and aperiod of 5.69 yr. Theorbital plane is inclined at an angle of 13.7° to theplane of the ecliptic.[1]
778 Theobalda is the namesake and largest member of afamily of 128 minor planets in the outer belt. The Theobalda asteroid family was likely formed6.9±2.3 million years ago from a collision-shattered parent body that had a diameter of around78±9 km.[4]
