In the main belt of asteroids, there exist pairs of asteroids that are on highly similar heliocentric orbits. They were discovered by Vokrouhlický and Nesvorný (2008) who showed that the asteroid pairs cannot be random coincidences of unrelated asteroids from the local asteroid population, but most of them must be genetically related pairs.
Being motivated by the progress in our knowledge and understanding of asteroid pairs, we underwent a thorough photometric study of a sample of nearly 100 asteroid pairs.
We report on the discovery that minor planet 5674 Wolff
is a fully-synchronous binary system with an orbital
period of 93.7 ± 0.2 h. The combined primary+secondary
rotation amplitude is 0.52 ± 0.02 mag. A lower limit on
the secondary-to-primary mean diameter ratio is D2/D1 =
