ESA releases detailed Images of Comet 67P/Churyumov-Gerasimenko

Detailed images of Comet 67P/Churyumov-Gerasimenko have been unveiled by the European Space Agency. The images are so elaborate that a physical model of the comet can be made using proper software and a 3D printer.

The images also provide an accurate estimate of 67P’s dimensions. Previously, it was claimed that the comet was about four kilometers in diameter. The new images indicate that the dimensions are 2.5 km by 2.5 km by 2.0 km around the head, the smaller of the comet’s two lobes, and 4.1 km by 3.2 km by 1.3 km for the body, the bigger lobe.

According to some earlier studies, the mass of the comet was about 10 billion tons and density of 400 kilograms per cubic meter. In every 12.40 hours, the comet completes one rotation. The surface temperature of the comet is between minus 68 degrees Celsius and minus 43 C. Its subsurface temperature is between minus 243 C and minus 113 C.

Rosetta has found water, carbon monoxide, carbon dioxide and ammonia, methane and methanol in gaseous form on the comet.

The further information on 67P includes its albedo in future. Albedo is the amount of light it reflects and the high resolution photos taken by Rosetta’s OSIRIS camera.

Rosetta is programmed to stay with 67P comet for over a year, as the comet’s orbit takes it closer to the Sun and then back out towards the farther reaches of the solar system.

The latest released images of the Rosetta comet allow fine 3D printing without any kind of outside help, but one needs to have the right software for the same. The photos are available as .wrl and .obj files from the agency’s website.

Rosetta comet seems to be almost recognizable by eye with the enormous amount of information and large visuals provided by Rosetta probe in the last few months.
