UGC 3730 or Arp 141 is a ring galaxy in the constellation Camelopardalis.
The galaxy lies about 130 million light years away from Earth, which means, given its apparent dimensions, that UGC 3730 is approximately 110,000 light years across.
The interaction has led one galaxy to turn into an asymmetric ring.
The companion, a lenticular galaxy, lies along the major axis of the ring and it is estimated to have a larger mass than the ring galaxy.
[2][3] The star formation rate of the ring galaxy is estimated to be 0.26 M☉ per year.
