761 Brendelia is a minor planet orbiting the Sun that was discovered by German astronomer Franz Kaiser on September 8, 1913, and named after Otto Rudolf Martin Brendel. It is orbiting at a distance of 2.8619 AU from the Sun with a period of 4.842 yr and an orbital eccentricity of 0.065297. The orbital plane is inclined at an angle of 2.16° to the plane of the ecliptic.
This is a member of the dynamic Koronis family of asteroids that most likely formed as the result of a collisional breakup of a parent body. It is an SC-type asteroid that is spinning with a period of 58.00±0.02 h.
