The asteroid 11118 Modra discovered at this observatory is named in the honor of the town.
About
The Astronomical and Geophysical observatory of Comenius University is located near the town of Modra and in the mountain range of Little Carpathians. The 3.5-hectare area contains several buildings and scientific instruments surrounded by beech forest. It lies on the middle trias quartzitic bedrock. It is accessible via a tourist trail or by the private paved road from Zochova chata. The main administrative building with the dome on the top contains the 0.60-metre Zeiss telescope with CCD camera and the 0.20-metre solar telescope with H-alpha filter. Within walking distance there are several buildings and pavilions with scientific devices, such as the magnetic pavilion (measurement of the Earth's magnetic field), the seismic cell with the seismograph, the solar telescope dome, the dome with the Schumann resonances registration device and the meteor pavilion of photographic and video meteor detection. The upper building with the 5-metre dome has a 0.70-metre reflecting telescope with CCD primarily for space debris research and registration devices for GPS and forward scatter meteor radar of the Bologna-Lecce-Modra network (transceiver-receiver-receiver). The lower building, standing next to the pond, consists of a small conference room and housing facility for guests. Since 1988, continuous weather and meteorological observations are done, therefore, the data provide a unique and homogeneous climate record of the site. In 2012 open-air amphitheater with seating, screen, projector and sound system was built for the public outreach purposes.

Education and research
As a part of the Comenius University, the observatory provides research opportunity for students, and the staff offers guidance for the Master and PhD theses. The research is mainly aimed at the interplanetary matter. Until January 2014, 175 numbered and 34 unnumbered asteroids were discovered at the observatory including two Near Earth Objects 2005 GB34 and 2008 UW5. The observing time is mostly assigned for the photometry of asteroids and comets and astrometry. The first observation of a transiting extrasolar planet in Slovakia was performed at the observatory. The solar physics researchers perform solar prominence and chromosphere features observations in the H-alpha line.
The observatory is also a member of the European bolide network and it has been developing its own TV meteor detection grid. Besides photographic all-sky cameras, fish-eye all-sky semi-automated meteor detection devices are located at Modra observatory, near Tesárske Mlyňany and in Kysucké Nové Mesto. In addition to meteor detection, real time all-sky cameras detect other phenomena, such as atmospheric sprites and elves (TLE).
Proposed Wide Field Survey (ADAM-WFS)
Based on the study on detecting close approaching Near-Earth Asteroids scientists of the department proposed a wide-field survey called "Automated Detection of Asteroids and Meteoroids - Wide Field Survey" (ADAM-WFS) aimed at discovery of small asteroids in the Earth vicinity and orbital debris.
In contrast to current asteroid surveys that are based on narrower field of view but deeper limiting magnitude, ADAM-WFS will observe entire visible night sky three times per night and identify moving targets. This survey is also considered as a low-cost project. It will use existing and verified methods and techniques, such as Moving Object Processing Pipeline (used by Pan-STARRS, NEOWISE, LSST). The proposed survey is similar to Asteroid Terrestrial-impact Last Alert System. If funded, the telescope will be housed in the Solar dome.
