Around the middle of Dragon's body, this is a deep-deep sky object at 3.2 degrees SSE of beta Draconis.
It's a very dimmed galaxy without NGC numbers, recognized by catalogue numbers of UGC10214, Arp 188 and so on.
The galaxy has a long axis of only 3 arc minutes and a brightness of 14.4th magnitude.
The galaxy has captured by the Hubble Space Telescope (HST) and its anomalous shape has been become clear.
The galaxy has a tail structure stretching toward east with a length of 3 arc minutes;
this fact has given this galaxy a nickname of "Tadpole Galaxy".
It's considered that the tail with a real length of 300 or 400 thousand light years has formed by a collision with a companion galaxy.
Another collided galaxy is concealed just behind UGC10214. It's estimated that the galaxy is about 45 millions light years away.
