C/1942 EA (Väisälä)

C/1942 EA (Väisälä) is a non-periodic comet discovered by Finnish astronomer Yrjö Väisälä on March 7, 1942. The designation "C/" indicates that it is a non-periodic comet; that is, it either has an orbital period of greater than 200 years or its orbit is hyperbolic. "1942 EA" denotes the year of discovery (1942) and the order within that year that it was discovered, according to the then-used designation system. "Väisälä" specifies the discoverer of the comet.

The comet's orbital parameters, determined through observation and calculation, reveal a highly eccentric orbit. Due to its non-periodic nature and the limitations of historical observations, the comet's future trajectory and potential return are uncertain. Precise details regarding its brightness and visibility during its 1942 apparition can be found in historical astronomical records.
