Pic shows comet SWAN25B which will next visit us in year 24,579
NASA has shared a picture of comet SWAN25B discovered on September 12. The picture was clicked during sunset in Mexico. The comet is quite bright, at around magnitude 7, with a long tail that stretches across 2 degrees in sky. NASA calculations show it completes an orbit around sun every 22,554 years. So, next it'll be visible in year 24,579.
