Young astronomers Aleksandar and Stefan Cikota, twins who are Physics students at the Zurich University, discovered an asteroid in March last year and named it (187700) Zagreb. Asteroid (187700) Zagreb moves at 18.2 km per second between Mars and Jupiter, while it takes 4.4 years for the asteroid to circle the Sun. The Cikota brothers have discovered over 2,300 new asteroids together with colleagues of the La Sagra Observatory.
