### Аннотация

A source of the non-thermal radio emission 3C58 was discovered in 1952 and identified with a remnant (SNR) of the supernova which had been observed in 1181. The structure of its radio brightness distribution is of the DOS Crab-like type. Like the Crab Nebula, the 3C58 includes the pulsar PSR J0205+6449, which can be observed at radio frequencies in the X-rays. The discovery of the pulsar was followed by a serious problem with identification of the radio source 3C58’s age. We discuss it in detail in [1]. Its dynamic age is found to be 5,400 years which has been defined by the pulsar damping period [2]. A closer age value is obtained through the average expansion rate of the nebula 3C58 which was de-termined after the results obtained in the VLA in1973 and 1998 were compared. It corresponds to the dynamic age of 5000 ± 2250 years [3]. Thus, it is found that the pulsar and the radio nebulae ages are almost the same and they are 4 or 5 times older than the supernova observed in 1181.
