Earth impact hazard

Asteroid 2024 YR4, first discovered on December 27, 2024, by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS), has been drawing much attention ever since it was found to (possibly) impact the Earth in less than a decade.

At night of September 26–27 RTT-150 optical telescope in Turkey observed asteroid Didymos and its smaller counterpart Dimorphos during the impact of DART mission (NASA). RTT-150 1.5-meter telescope is part of ground-based facilities in support of Spektr-RG project.
