What Happen If Ceres and Vesta Will Collide

Calculations of the orbital evolution of two major objects of the main asteroid belt, the dwarf planet Ceres ans the asteroid Vesta. showed that in the future they may collide.The collide of Ceres and Vesta possible with a probability of 0.2% per billion years.Laskar and his colleagues conducted computer simulations of the evolution of the solar system, considering the behavior of the eight planets, Pluto, Ceres, and the four largest asteroids Pallas, Vesta, Iris and Bamberg, located in the main asteroid belt between Mars and Jupiter

The Rosetta Spacecraft’s First Images of Comet 67-P/Churyumov-Gerasimenko

The European Space Agency’s Rosetta spacecraft pursued the comet 67-P/Churyumov-Gerasimenko for more than seven years. And now finally Rosetta can take a series of 52 pictures from a distance of about 101 million miles (163 million kilometers) from comet 67-P/Churyumov-Gerasimenko.67-P/Churyumov-Gerasimenko is about 2.4 miles (4 km) across and completes one orbit around the sun every 6.6 years.
