57. COMETS 



Comets are composed of a head or nucleus, and a tail which 

 varies in length, increasing as the comet approaches the sun. 

 The volume of a comet is extremely large, almost passing 

 human comprehension. Yet the mass is very slight, and in 

 the largest comet is only a small fraction of the earth's mass. 

 The light of a comet is due partly to light reflected from the 

 sun, and partly to some electrical disturbance which is not 

 well understood. They are composed, doubtless, of large 

 aggregations of very small meteors acting as one large body. 

 It is probable that if the earth were struck by a comet, the 

 shock of collision would be very slight and little damage 

 would be done.
