Comet 67P was formed through merger of 2 separate pieces: Rosetta
Q. Which comet is made of a larger and smaller lobe when two completely formed, distinct objects merged together, according to NASA’s Rosetta?- Published on 05 Oct 15a. 67A
b. 67C
c. 67H
d. 67P
ANSWER: 67P
Rubber duck shaped comet 67P/Churyumov–Gerasimenko (67P) is composed of a larger and smaller lobe separated by thin, neck region resulting from the merger of distinct objects. Till this time, it was unclear whether comet 67P was formed by the fusion of 2 objects or a concentrated localised erosion of a single object. Scientists have demonstrated that its peculiar shape is the result of low speed collision between completely developed comets, as per high resolution images taken from OSIRIS/Optical, Spectroscopic, and Infrared Remote Imaging System between August 6, 2014 and March 17, 2015 to find out more of the layers of material seen all over the nucleus.
