Some General research where going on Space by our NASA team.We all have a wish to be travel on the shy but some people have gone through them,with their hard work and courage.As we go on to space there are other objects revolve around the sun as we have study earlier in our childhood days.We know earth is surrounded by Ozone layer and sometimes moon used to cover the earth on a night time and so on.......
There are other small bodies which revolve our earth,Mars,Venus,Mercury,Sun.....The other small bodies are called as Asteroid.Asteroid are small bodies,composed of rock and iron,that were unable to form distinct planets when the solar system was born.They orbit the Sun,most of them travelling in a belt between Mars and Jupiter.
Do u know Y the asteroids are in a circle and in order??
Because Jupiter's gravitational pull can send asteroid into erratic orbits it means in a order and in circular rotation....It causing them to collide with planets and other asteroids.
