Such a close encounter is rare but not unprecedented. In some cases the comet will only pass near the Sun once. It is said that when the age of this earth was one crore years, a massive meteor had smashed into it causing it to split into umpteen numbers of parts. The average temperature of the surface of a typical asteroid is minus 100 degrees F (minus 73 degrees C). The core consists of accessory fragments of an earlier eruption, accidental fragments of country rock or, in rare cases, bits of lava formed earlier during the same eruption." [145] The image shows a chain of craters on Ganymede.

The meteors appear to originate from a single point, called a 'radiant', in the constellation of Perseus, hence the name of the shower. The meteoroid when it falls down into the earth atmosphere it burns up into a meteor or a shooting star. So, one inch in the model represents a hundred thousand miles in reality.

Akarsh_Valsan: Have any asteroid or any comets ever coillided with sun? Priceless observational information derived from the spacecraft were made quickly available, giving researchers such insights as time, a location, height above the surface, as well as light-curves to help pin down the amount of energy churned out from the fireballs. Other observations of this asteroid reveal that it appears to have different densities of material below the surface in its two ends - it isn't made of only one type of rock.

They are leftovers from the beginning of the solar system. The Nine Planets contains facts and historical information about comets, meteors, and the Kuiper belt and Oort cloud. The most amazing result was that the smaller of the two bodies making up the nucleus was far more active than the larger one. It also appears that like the planets Vesta has a layered structure, with lower density material near the surface, and denser material near the core.
