Mikhail Maslov, an engineer at the "Vega" observatory of Novosibirsk State University, stated that meteorites 15–20 meters in size are still rarely registered by tracking systems. Such objects are too faint to be reliably detected before entering the atmosphere — only in isolated cases, if lucky.
This creates risks of a repeat of the situation with the Chelyabinsk meteorite, which unexpectedly entered the atmosphere in February 2013. At that time, a celestial body with a diameter of about 18 meters and a mass of about 10 thousand tons exploded at an altitude of approximately 20 kilometers. The shock wave damaged residential buildings and industrial facilities in several districts of the Southern Urals.
Earlier, the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences stated that objects approaching from the Sun, similar to the Chelyabinsk meteorite, are still impossible to detect in the daytime sky. In Russia, a project called "Daytime Asteroid Detection System" (SODA) was discussed, which involved launching a satellite to observe the planet from the direction of the Sun. This would allow detecting a threat at least several hours before impact. However, the discussions did not progress further.
Scientists urged to include such an initiative in the national project "Cosmos", as the appearance of a second such asteroid could happen at any moment.
