These changes included evolving patterns of circular shapes in smooth terrains that at some point grew in size by a few metres per day. A fracture in the neck region was also observed to grow in size; boulders tens of metres wide were displaced, sometimes travelling more than 100 metres; and patches of the ground were removed to expose new features. A number of collapsing cliffs have also been observed.

On 22 October, about a month after the photograph was taken, he discovered that the object could not be Comas Solà, because it was about 1.8 degrees off the expected position. Further scrutiny produced a faint image of Comas Solà at its expected position on the plate, thus proving the other object to be a different body. 9416: 1225:) moved Churyumov–Gerasimenko's perihelion inward from 2.7 AU (400 million km) to 1.28 AU (191 million km), where it basically remains today.

With each orbit the comet loses matter, as gas and dust are evaporated away by the Sun. It is estimated that a layer with an average thickness of about 1 ± 0.5 m (3.3 ± 1.6 ft) is lost per orbit as of 2015. The comet has a mass of approximately 10 billion tonnes. 1921:) gas surrounding the comet. Solar system models suggest the molecular oxygen should have disappeared by the time 67P was created, about 4.6 billion years ago in a violent and hot process that would have caused the oxygen to react with hydrogen and form water. Molecular oxygen has never before been detected in cometary comas. 1296:
