Paris, 6 February 2016, 10:45 – REGNUM The European Space agency (ESA) has published new data on the comet 67P / Churyumov-Gerasimenko. Appropriate publication is made in the journal Nature on February 4.
Scientists estimate the comet’s mass is about 10 billion tons. This is 20 million times heavier than the largest man-made object in space -. International Space Station,
However, the researchers point out that this dotachano little weight for a celestial body of this size, the comet Churyumov-Gerasimenko. It turned out that about 70-80% of its volume occupied by small voids. The total density of the comet is the same as in traffic jams, wood or airgel.
At first, astronomers assumed that inside a comet can be a big cave. However, after a thorough study of the gravitational field of the comet, scientists have concluded that the largest caves in the depths of the comet is not, and its porous structure.
Most of the comet bowels takes dust. She was in the comet Churyumov-Gerasimenko in a couple times more than the ice crystals. Since the comet formed during the birth of the Sun, Earth and other planets in the solar system, the discovery of the high friability and porosity comet bowels says that the primary matter of the solar system with similar properties.
Detail explore the comet Churyumov-Gerasimenko fails due to the spacecraft “Rosetta”. This device, developed by ESA in cooperation with NASA’s, was the first terrestrial spacecraft, which entered the orbit of the comet. In addition, in the framework of the “Rosetta” November 12, 2014 there was the world’s first soft landing lander -. Probe “Fila” on the surface of the comet
