| | Borrelly, Comet (19P/Borrelly) |
 | | It became only the second comet to have its nucleus photographed by a space probe when Deep Space 1 flew passed it at a distance of only 2,170 km on September 22, 2001. |
 | | Scientists were surprised when the probe revealed that, though the solar wind flows symmetrically around the coma of Comet Borrelly, the nucleus lies to one side, shooting out a great jet of material that forms the cloud that makes the comet visible from Earth. |
 | | Borrelly seems to be broken into two pieces, canted at about 15°, that appear to chaff against each other, raising what look like compressional ridges at the boundary of the two sections. |
