A 2.4 mile-wide (4km) region on the 'head' of comet 67P/Churyumov-Gerasimenko has been revealed as the spot for the daring landing of Rosetta's Philae probe. The high-risk manoeuvre, if successful, will be the first time in history that a probe has been landed on a comet. Scientists at mission control in Germany hope the spider-like probe will send back data that could answer questions on the origin of Earth's water and perhaps even life. Scroll down for videos and animation The relatively smooth landing region, identified for the moment simply by the letter 'J', is located on the smaller of the duck-shaped comet's two lobes.

The region, named site J, is around 2.4 miles (4km) at its widest point
@highlight
A back-up site, site C, has also been revealed on comet's larger lobe
@highlight
Sites were chosen as they are relatively flat and gain more sunlight

Rosetta will launch  Philae robot 6 miles (10km) from comet Comet 67P
@highlight
The 220lb (100kg) lander will reach the comet's surface on 11 November

Spider-like probe could answer questions on the origin of life on Earth
If all goes to plan, @placeholder will then make a gentle landing on the comet at walking pace, using screws and harpoons to lower and secure itself on the surface.
