Orbital characteristics
Tisiphon is drawn in the outer part of the Main belt of asteroids at an average distance of 3.352 a. e. (501.5 million km) from the Sun. Its orbit has a moderate eccentricity of 0.09094 and an inclination of 19.111 Β°. Thus, the maximum distance from Tisiphon to the Sun is 3.657 a. e. (547.1 million km), the minimum - 3.048 a. e. (455.9 million km).
The absolute magnitude of Tysiphons is 8.3 m . Its visible luster during the synodic period varies between 12.8-15.0 m [2] .
The period of revolution of Tysyphon around the Sun is 6.138 years (2242 days).
Physical Characteristics
The average diameter of Tisiphon is 115.53 Β± 2.2 km, and the albedo is 0.0634.
The circulation period of Tysiphons around its own axis is 8.824 Β± 0.009 h (8 h 49 min) [3] .
