SRG/eRosita detected more than 1.5 million X-ray sources on one hemisphere including a million quasars and AGNs and 200 000 stars after 4 scans of the entire sky. Many of these sources are strongly variable. Among them are more than 80 TDE. Surprisingly GAJA detected strong proper motion for more than 500 X-Ray extragalactic objects from SRG/eRosita catalog. I plan to mention possible interpretations of this result.
In addition, eRosita discovered more than twenty thousand clusters of galaxies with hot intercluster gas and two interesting supernova remnants. The central part of one of them radiates mainly in the line of Fe XVII. Both these remnants do not demonstrate any radio, gamma, or optical radiation.
