721 Tabora is a minor planet orbiting the Sun. Tabora was named at a conference in Hamburg, Germany in 1913. The name was chosen because the conference was held aboard the passenger cargo liner Tabora of the Deutsche Ost-Afrika Linie.[2] The asteroid is orbiting at a distance of 3.55 AU from the Sun with a period of 6.69 years and an eccentricity (ovalness) of 0.12. The orbital plane for is inclined at an angle of 8.3° to the plane of the ecliptic[1] It is a member of the Cybele group in the outer belt, located close to the 7:4 and 16:9 orbital resonances with Jupiter.[3]

Photometric observations of this asteroid made during 2005 were used to produce a light curve showing a rotation period of 7.982±0.001 h with a brightness variation of 0.28 in magnitude.[4] This is a low albedo D-type asteroid showing the characteristic featureless, reddish spectrum of that taxonomic class.[3] It spans a girth of approximately 76 km.[1]
